Can musl libc be built on OS X?

I'm trying to build musl-libc on a machine running OS X 10.11.5. Unfortunately, I get the following error while running make:

clang: warning: optimization flag '-fexcess-precision=standard' is not supported
clang: warning: optimization flag '-frounding-math' is not supported
<inline asm>:6:1: error: unknown directive
.weak _DYNAMIC 
^
<inline asm>:7:1: error: unknown directive
.hidden _DYNAMIC 
^
2 errors generated.
make: *** [obj/crt/Scrt1.o] Error 1

I'm using Clang 7.3.0 (703-0-31) and I'm using the source pulled from the musl repo at git://git.musl-libc.org/musl.

These are OS X assembler errors and this means that it is different from a GNU as in the way it understands special weak and hidden symbol definitions in object files.

While .weak directive is possibly supported by Apple as as .weak_definition, .hidden is an ELF specific (OS X uses Mach-O binary file format).
