    cross-build: Define __*int*_t and include sys/cdefs.h
    
    FreeBSD assumes that sys/types.h includes sys/cdefs.h, so add it here.
    FreeBSD also needs __*int*_t defined for software we bootstrap (a lot of
    it). GLIBC defines these, but musl does not, so we have to define them
    here, even though it looks backwards. There's no good #define to key off
    of, so use !defined GLIBC since on Linux defacto there's only two libc
    implementations.
