Subject: Cross-compiling Musl with Clang's integrated assembler

Hi all,

I'm trying to build Musl for an ARM target on an x86_64 host using Clang. It seems some of the Musl
assembly uses the LDR pseudo instruction that the Clang integrated assembler doesn't understand:

     $ clang -target arm-none-eabi -integrated-as -c crt/arm/crt1.s
     '+soft-float-abi' is not a recognized feature for this target (ignoring feature)
      crt/arm/crt1.s:10:9: error: unexpected token in operand
             ldr a4,=_fini
      ...

Is this configuration supported? Perhaps Musl is never intended to be built by Clang's assembler.

Thanks,
Matt

clang version: 3.4-1ubuntu3
