I didn't look at the mesa sources, but are you sure this does the right
thing on uClibc w/locales? Normally you need to #include <features.h>
for the __UCLIBC_* defines - E.G.

./output/host/usr/bin/arm-linux-gcc -dM -E - < /dev/null |grep -c UCLIBC
0

echo '#include <features.h>' > dummy.c
./output/host/usr/bin/arm-linux-gcc -dM -E dummy.c |grep -c UCLIBC
76
