instead of sigprocmask.
In the process, discover that error handling for
ML_(do_syscall_for_client_WRK) on all platforms has always been
broken, in the sense that the sigprocmasks (which are important) could
silently fail. This commit fixes that up too (only on ppc64-linux at
the moment, so all other platforms are probably broken now).

do_syscall_for_client_WRK() needed a bigger stack to avoid the linkage area.
always use dot_prefix for label calls
not wrapping assembly with
.section ".text"
...
.previous
- ppc64 doesn't like it... seems we can't 'stack' more than one section to pop off with .previous ?
