stdc-predef.h and musl-gcc

Hi,
when used with the musl-gcc interface, we are missing some of the
standard macros. A simple add to the spec file for preloading
stdc-predef.h solves the problem for me.
Thanks
Jens

Hmm, I suppose -nostdinc is what's suppressing it from happening by
default? Is there a reason for the two spaces above?
