This was reported as uClibc test suite failures of tst-mqueue3 and
tst-mqueue5.
The syscall args were getting clobbered, so use scratch regs which are
not used for syscall args

Similar to musl libc a single libc has many benefits and solves
some open issues with uClibc-ng.
- no pthread_mutex_* weak symbols exported anymore
- applications no longer failing to link when either
-lrt or -lpthread are missing for dynamic and static linking mode
- smaller C library
- slightly better runtime performance

Simplify and use generic lowlevellock.

Commit 2d9740a65a "uclibc: nptl: fix __lll_lock_wait_private multiple definition"
did a sweeping change which did for all in tree arches at that time (ARC
wasn't)

Automatic patching via two oneliners by Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>:
sed -i -e 's/[[:space:]]pt-vfork\.[csS]//' -e '/^ASFLAGS-pt-vfork\./d' $(git grep -l pt-vfork libpthread/nptl/sysdeps)
find libpthread/nptl -name "*pt-vfork*" -exec git rm {} \;
