Addresses PR 57693

Log message:
pari: Remove broken --with-fltk argument.

In the 13 years since this was added, pari may have changed as any --with-fltk
argument, even =no, enables fltk and breaks the build on e.g. macOS.

Log message:
Mass-change BUILD_DEPENDS to TOOL_DEPENDS outside mk/.

Almost all uses, if not all of them, are wrong, according to the
semantics of BUILD_DEPENDS (packages built for target available for
use _by_ tools at build-time) and TOOL_DEPEPNDS (packages built for
host available for use _as_ tools at build-time).

No change to BUILD_DEPENDS as used correctly inside buildlink3.

As proposed on tech-pkg:

  Changed
HC   1- faster implementation of eulervec + cache result
     2- sumnummonieninit(,1): faster algorithm (complex step)
     3- atanh(rational) now uses binary splitting
BA   4- FqV_to_FlxV, FqC_to_FlxC, FqM_to_FlxM: replaced by
        ZXC_to_FlxC, ZXM_to_FlxM
     5- FpM_intersect and Flm_intersect now guaranteed to return an
        Fp-basis; use FpM_intersect_i if you only need a generating set
     6- ZXX_to_Kronecker -> RgXX_to_Kronecker, ZXX_to_Kronecker_spec
        -> RgXX_to_Kronecker_spec
     7- [libpari] nbessel -> ybessel
     8- faster implementation of mfinit and mfbasis in weight 1
     9- ZabM_ker: replace final exact check by probabilistic check modulo a
        63-bit prime
    10- [libpari] ZC_u_divexact -> ZC_divexactu
    11- unify real and imaginary binary quadratic forms, include discriminant
        types t_QFI and t_QFR are replaced by t_QFB
    12- allow Qfb([a,b,c]) and Vec(t_QFB)
    13- qfbredsl2(q, S): change format of S: was [D,isD], is now isD
BA  14- [libpari] gp_read_stream now return NULL when EOF is reached (was gnil)
    15- elltwist now returns an ellinit, and accepts the same input formats
        as ellinit ([a1,a2,a3,a4,a6], [a4,a6], Cremona label)
    16- gen_search / vecvecsmall_search: remove flag; the result is now
        positive if the element is found else -i if element should be
        inserted at position i.
    17- allow t_COL of objects in gconcat1 / shallowconcat1
    18- [libpari] Z_smoothen now uses (and returns) t_VEC arguments.
        Use Z_lsmoothen to input small primes as a t_VECSMALL.
    19- poliscyclo: replace Bradford-Davenport's Graeffe method by their
        invphi algorithm (much faster)
BA  20- [libpari] QXX_QXQ_eval renamed to QXY_QXQ_evalx
    21- [libpari] ZX_Zp_root(f,a,p,): assume 0 <= a < p
BA  22- [libpari] gen_factorback now take an extra parameter one.
    23- [libpari] mplambertx_logx, mplambertX, mplambertxlogx_x
    24- [libpari] absZ_factor_limit_strict no longer guarantees that q is
        composite: this is useless for applications and possibly expensive
    25- default(debugfiles,) is now obsolete, use setdebug("io",)
    26- [libpari] quadclassno now has a second argument (to recover the
        attached fundamental discriminant)
    27- faster qfbclassno for non fundamental positive discriminants
        (use quadunitindex)
    28- removed appa.tex from users.dvi; inline the text in INSTALL.tex
    29- divrunu, divgunu: use a single division in all cases (faster even if
        denominator has 2 words)
    30- allow random(negative integer N) -> a random integer in [-n,n], n=|N|-1.
    31- allow sqrtint and sqrtnint for nonnegative real number argument
    32- allow logint for positive real number argument
    33- improve gamma and lngamma for t_FRAC inputs
    34- renamed normalize -> normalizeser
    35- nfinit/nfdisc/nfbasis: use lazy factorization by default [#2326]
    36- in idealtyp(ideal, fa), allow setting fa to NULL
BA  37- system now return the shell return value.
    38- allow valuation(x) when x is a t_PADIC, a t_POL or a t_SER
    39- libpari function precision() now always return a 'prec' (integer > 2).
        It used to return 2 for real 0 of non-negative exponent.
    40- grndtoi(GEN x, long *e): allow setting e = NULL
BA  41- [libpari] pari_thread_start: do not allow threads started this way to
        launch more threads.
BA  42- genus2red: 3rd component is now a pair [P,Q] such that y^2+Q*y=P is
        minimal everywhere.
    43- faster implementation of binomial

  Removed
     1- [libpari] obsolete functions qfi, qfr, qfi_1, qfr_1, redreal,
        redrealnod, rhoreal, rhorealnod, qfrcomp, qfrcompraw, qfrsqr,
        qfrsqrraw, qfisqrraw, qficompraw, qfipowraw, qfipow, qficomp,
        qfisqr, redimag
     2- [libpari] obsolete types t_QFI, t_QFR
     3- [libpari] nfinitall is now obsolete; use nfinit with the same arguments
     4- [libpari] order is now obsolete; use znorder
