Subject: Make errno-setting libm templates include errno.h.

Various type-generic libm wrapper templates, as used for float128, set
errno but do not include errno.h.  I presume they must get an implicit
include from some internal header on powerpc64le; they don't get such
an implicit include on x86_64.  This patch adds the missing includes
of errno.h to each such wrapper.

Tested for x86_64 (in conjunction with float128 patches).
