I've also included your patches in yesterday night's full bootstraps and
found an additional issue: with -j96 (sparc-sun-solaris2.12) resp. -j24
(i386-pc-solaris2.12), I get many (74 resp. 100) instances of

in mail-report.log.

As I've said before, the parallelization of ms-sysv.exp runs may be a
bonus, but is certainly separate from this PR and thus should be split
out: a sequential run of ms-sysv.exp (-m64/-m32) on x86_64-pc-linux-gnu
takes just 3m36 on a 2.67 GHz Xeon X7542 with default checking options;
nothing to worry about for the common case.
