[PATCH][libgloss] Use POSIX regex character classes instead of perl regex classes

Hi All,

This fixed the build on systems using BSD sed instead of GNU sed where the semihosting
build would fall over because the sed expression wouldn't match.

The previous patch used perl style character classes for space \s while the new one
uses the POSIX style [:space:] instead.

OK for master?

PS. I don't have commit rights so if OK can someone commit for me?

Thanks,
Tamar
