Subject: fix syscall asm constraints for arm too
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=075fdb909b7692df7f3c440331114a754267a167

fix syscall asm constraints for arm too

no problems were detected so far, but the constraints seem to have
been invalid just like the mips ones.
