https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sys-devel/gcc-11.2.1_p20220115 does not respect LDFLAGS. Discovered on: amd64 (internal ref: ci) NOTE: To reproduce this issue you may want to set LDFLAGS="${LDFLAGS} -Wl,--defsym=__gentoo_check_ldflags__=0". If this is not something about c/c++ context you may want to see this bug as an hint to hide the QA warning (with QA_FLAGS_IGNORED) where is not possible to respect LDFLAGS.

I was pretty sure we had a bug for this but I can't find it right now.

This consistently ends up saving at least 15 minutes for me on a fast amd64 machine and should save more on slower machines and architectures. There's only any risk here if the host compiler is ancient/very buggy and even then, you get a failed bootstrap later on. The GCC developers, per the linked bug, end up using STAGE1_CFLAGS="-O2" anyway to speed up the process so it's not like this is untested at all. mattst88 actually brought this up.. 10 years ago (bug #477548). Let's try make that right now. * Respect LDFLAGS for target libraries for native builds. Not touching this for cross builds, at least for now, as it's a bit more delicate. (Unfortunately, we have to put a hack in here for now until we can fix multilib.eclass - see bug #914881).
