+[PATCH] git-version-gen: skip "-dirty" check when appropriate
+
+* build-aux/git-version-gen: Don't run any git commands
+when the version comes from .tarball-version.  Prior to this,
+we would run git update-index --refresh even from a just-unpacked
+tarball directory, and that could affect a .git/ directory in a
+parent of the build directory.  Reported by Mike Frysinger.

+uclibc defines __GLIBC__ but it does not expose struct shed_param as much as glibc
+and is not needed too per standard. gnulib attempts to use it but we have to account
+for it because in this case uclibc does not behave like glibc.
