  - all:
    Implement 'cpuflags -v' which indicates the values used to determine flags
    Sync the latest fixup options for older gccs
  - cpuflags.NetBSD:
    Use -march=pentium3m and -march=pentium4m for gcc 3.4.x
    Set -mcpu=hypersparc for RT620/625 and -mcpu=cypress for L64811
  - cpuflags.Linux:
    Handle two different Celeron cases (thanks to Marc Recht & Jeremy C. Reed)

Log message:
Update cpuflags to 0.74:
    NetBSD/Linux:
	athlon-4, athlon-mp, athlon-tbird, and athlon-xp should fall back to
	athlon in gcc3, and only pentiumpro in 2.95
    Linux:
	Identify "AMD Athlon(tm) XP "* - thanks to Sebastian Prause

Log message:
Update cpuflags to 0.73:
	sync cpuflags.Linux with cpuflags.NetBSD, at least optimise for
	Duron in cpuflags.Linux

Log message:

Log message:
Update cpuflags to 0.70
    Correctly 'downgrade' -march=pentium3 -mno-sse to -march=pentiumpro
    for older compilers. Should address PR pkg/25759

Log message:

    Exclude -fomit-frame-pointer for {firefox,thunderbird}{,-gtk2}

Log message:
Update cpuflags to 0.67:
	- Add 'Intel Mobile Pentium 4' from Benedikt Meurer
	- Fix exclusion of -fomit-frame-pointer mozilla-gtk2 in optimize_gcc.mk

Log message:
iupdate cpuflags to 0.66:
	Avoid -fomit-frame-pointer for mozilla-gtk2 & galeon-devel

Log message:
Update cpuflags to 0.65.
	Use -dumpversion with gcc rather than mangling -v output. Suggested
	by mrg. Located copy of egcs to confirm output still correctly
	mangled in that case :)

Log message:
Update cpuflags to 0.64:
	- Do nothing on x86_64 (for now). Thanks to Wolfgang S. Rupprecht
	- Digital AlphaPC 164SX. Thanks to HATANO Hiromichi.
	- Intel Pentium/MMX & Unrecognised Athlon XP. Thanks to Kimmo Suominen
	- Mips update for gcc 3.1 and later. Thanks to Andreas Yankopolus
	- Handle converting flags for old gcc versions recursively. Most
	  excessive case would be using cpuflags on a k6-3 win gcc 2.89 which
	  would map -march=k6-3 -> -march=k6 -> -march=pentium -> -march=i486
