Support for musl libc?

[rhencke]

Would you consider support for musl libc? (or be open to PRs that added support for it?)

(I actually love using ctypes.sh - it's.. actually really good.)

What doesn't work with musl libc?

Would be more than happy to get PRs, or help fix whatever is broken.

Here are some of the things currently preventing compiling against musl.

Location	Issue
ctypes.sh/src/struct/dutil.h Line 44 in 091e644 static __always_inline int fls(int x)	no __always_inline in musl (could use __attribute__ ((__always_inline__))?)

I could start to take a stab at some of these, make a preliminary PR? I'm sure I'm gonna end up taking you up on that offer for help at some point along the way here.. :)
