Issue: dev-libs/bitset-2.8.4-r1 does not respect CFLAGS.
Discovered on: amd64 (internal ref: tinderbox)

NOTE:
To reproduce this issue you may want to add "-frecord-gcc-switches" to CFLAGS/CXXFLAGS/FFLAGS/FCFLAGS. If this is not something about c/c++ context see this bug as an hint to hide the QA warning (with QA_FLAGS_IGNORED) where is not possible to respect CFLAGS.

Somehow CFLAGS are not detected by package buildsystem, thus it tries to put 'good' CFLAGS itself.

I can not reproduce it on my system, i just do not have strings like:

checking whether C compiler accepts -malign-double... yes
checking whether C compiler accepts -fstrict-aliasing... yes
checking whether C compiler accepts -ffast-math... yes

during configure stage, and those options does not added into CFLAGS.

But i discovered option --enable-portable-binary, which, based on it's description will reduce 'smartness' of buildsystem in case if it can not detect user requested CFLAGS.

Please try dev-libs/bitset-2.8.4-r2, thanks in advance

ci has reproduced this issue with version 2.8.4-r2 - Updating summary.

I have narrowed down problem to sys-devel/autoconf:2.71 -> when it is used, CFLAGS  are ignored by package buildsystem
