I'm not sure this is a bug or if I'm making some kind of mistake, but using
gcc-4.2.2 and the 2.6.29.1 kernel, when glibc-2.9 is compiled with:
CFLAGS="-march=i486 -mtune=i686 -pipe -O2"
../glibc-2.9/configure --prefix=/usr --disable-profile --enable-add-ons --
enable-kernel=2.6.16
It will not boot on i486 or i586 machines, but will boot on i686 machines and
the atom n450.
When glibc-2.9 is compiled with CFLAGS unset and:
echo "CFLAGS += -march=i486 -mtune=i686 -pipe" > configparms
../glibc-2.9/configure --prefix=/usr i486-pc-linux-gnu --disable-profile --
enable-add-ons --enable-kernel=2.6.16
..it will boot on i486, i586, i686 machines, but although it will boot on an
atom n450, it gives these errors:

oss_hdaudio 0000:00:1b.0: PCI INT A -> GSI 16 (level, low) -> IRQ 16
Is this a bug or is there a smarter way to compile to work on these machines?
