> Is this because I manually changed BOOT_CFLAGS as passed to make?
As previously said, you ought to avoid fiddling with BOOT_CFLAGS in any case.
Configure --with-build-config=bootstrap-lto --with-fpmath=sse --with-arch=xxx
and so on, and just type "make".

Probably because you're also fiddling with configure checking options. Avoid
doing that if you aren't familiar with them.
