+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.
