prepend "__". Unfortunately, when we #undef things, we do not prepend the
"__". This results in collateral damage to unsuspecting applications as we
undefine random unrelated macros. Oops.
For example, when compiling xfree86, libGLcore.a defines MALLOC for its own usage.
But include/bits/uClibc_config.h then does an
#undef MALLOC
#define __MALLOC_930716__ 1
which inadvertantly trashes the define from libGLcore.... Ouch.
The autogenerated include/bits/uClibc_config.h should instead have
contained:
#undef __MALLOC__
#define __MALLOC_930716__ 1
This patch makes that happen.
