Sure - edit the CFLAGS settings in /usr/src/linux/Makefile and
/usr/src/linux/arch/i386/Makefile.
You'll probably want to remove the -fno-strength-reduce from
arch/i386/Makefile as well as adding the other flags -
-fno-strength-reduce is no longer required with anywhere near recent
versions of gcc/egcs.
For my own kernel, I'm using gcc 2.95.2 with the flags
-O6 -fomit-frame-pointer -fexpensive-optimizations -ffast-math
-fstrict-aliasing -mpentiumpro -march=i686
(This is optimizing for speed, possibly at the cost of stability. Works
for me, but I hardly ever have an uptime of > 2 days (I tend to update the
kernel often...))
