[Bug bootstrap/30810] New: top-level BOOT_CFLAGS not being used for bootstrapping

["sdack at gmx dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When I pass BOOT_STRAP="-march=athlon -O2" on the command line of make to
bootstrap gcc then they are not being used. The flags for bootstrapping always
default to "-g -O2".

I believe this is due to BOOT_CFLAGS missing in the top-level's Makefile lists
for variables to pass on to sub-level Makefiles. Atleast that list does not
contain BOOT_CFLAGS so how should this variable get there?

This is not specific to 4.1.2. I think I saw this already in 4.1.1.

The reason why I need it is because I want to create a profiled bootstrap with
a few more optimizations so that an optimised executable will be installed when
running "make install".
