i can see this option being used in the later step in "crosstool" to build
glibc and linuxthreads.  the warning i'm getting is from the earlier step
for installing glibc headers which is necessary for building the boot gcc
compiler.

so while i can certainly that option to the earlier step, i'm reluctant to
hack the crosstool code without knowing why *that* script doesn't include
the option in the earlier step, or whether it's meant to be that way and i
can just ignore the warning.
