uClibc list is the place to go for buildroot atm ;)

here's a pdf i found a while back:
http://dev.gentoo.org/~vapier/mudflap.pdf

in theory it's actually a pretty good idea ... even better in that it'd be 
part of the official gnu toolchain

either way, buildroot should have it disabled for uclibc targets ...

weird ... when do you hit this error ? during the gcc stage1, gcc stage2, or 
the cross-compiled native compiler ?

it's in 0.9.27 and 0.9.28 so it really wasnt removed
