Subject: musl: introduce dummy function for gnu_get_libc_version()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=03d0fa4e4f824b725e3f250f70f4725c569c60a4;p=thirdparty%2Fsystemd.git

musl: introduce dummy function for gnu_get_libc_version()

As the header gnu/libc-version.h and gnu_get_libc_version() function
are glibc specific, and musl does not provide them.
