cross-build: Define __*int*_t and include sys/cdefs.h

Browse Source 
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.

/*
* MUSL doesn't define the __intXX_t that FreeBSD does, but many of our headers
* assume that will always be present. Define them here. We assume !defined
* __GLIBC__ is musl since musl doesn't have a define to key off of. Thesee
* typedefs look backwards, but it's not circular because MUSL never defines the
* __*int*_t. Also, we don't have to work in the kernel, so it's OK to include
* stdint.h here.
