Subject: [PATCH] Use generic errstr.go implementation on musl
glibc provides two version of strerror_r() depending on a feature test
macro. The first is the XSI-compliant version which returns an int, the
second is GNU-specific and returns a char pointer.
Similarity, gcc's libgo provides two implementations of Errstr() both of
which use strerror_r(). On Linux, it is assumed that the GNU-specific
strerror_r version is used. However, musl only provides the
XSI-compliant version of strerror_r. This patch enables the generic
Errstr() implementation which also uses the XSI-compliant version of
strerror_r.
