Log message:
gcc{48,49,5,6,7,8}: In the case of a "system GCC", detect if the system
libgcc is newer than the one about to be installed. If so, don't install
the libgcc.

Having an older libgcc appear in the lookup may result in binaries not
running, as they need symbols from the newer libgcc.
Such a case is PR pkg/54506.

Leaves SunOS unchanged, by request from jperkin.

Log message:
gcc{48,49,5,6}: add patch to avoid fragile include guard logic
for ansi.h on netbsd.
gcc{7,8}: document same patch that already existed was upstreamed.

This patch is necessary to build GCC on NetBSD >= 9.0, since changes
to ansi.h resulted in not using the same include guards.

Fixes PR toolchain/54362

Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.
