commit: http://git.uclibc.org/uClibc/commit/?id=23b99061c80f6979cdf873e534f6cd213b460781
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

Rename EXTRA_CPPFLAGS to UCLIBC_EXTRA_CPPFLAGS and make them override
previous flags (by appending - not prepending - them to the other flags).
