Hi,

when trying to build musl on armhf, the build fails with the following
error (gcc 6.3.0), which is also seen on the Debian build servers [0]:

> gcc -std=c99 -nostdinc -ffreestanding -fexcess-precision=standard -frounding-math -Wa,--noexecstack -D_XOPEN_SOURCE=700 -I./arch/arm -I./arch/generic -Iobj/src/internal -I./src/internal -Iobj/include -I./include  -Os -pipe -fomit-frame-pointer -fno-unwind-tables -fno-asynchronous-unwind-tables -ffunction-sections -fdata-sections -Werror=implicit-function-declaration -Werror=implicit-int -Werror=pointer-sign -Werror=pointer-arith -include vis.h -Wa,-mimplicit-it=always -Wa,-mthumb  -fPIC -c -o obj/src/thread/arm/atomics.lo src/thread/arm/atomics.s

> Makefile:158: recipe for target 'obj/src/thread/arm/atomics.lo' failed

On other architectures it builds fine.
Does someone know what the issue is?

Kind regards,
