Hi build machinery maintainers,

Paolo's patch on Feb 20th broke the profiledbootstrap
by building crt* with -fprofile-generate during stageprofile,
which makes the compiler from stageprofile unable to link any executable
(unless you pass -fprofile-generate, that is).

The below patch fixed the problem (along with my other pending patch
on libiberty/cplus-dem.c). Tested by doing a profiledbootstrap on
i686.
Ok for mainline ?

Why is it necessary for all-target-gcc? If it's not really necessary, maybe it's better to remove the flag in libgcc's makefile (see audit trail of PR32009 for an example).

Sorry for the breakage.

Paolo
