-Subject: [PATCH 9/9] ld: replace glibc dynamic linker with musl
-
-Rework of patch by Khem Raj <raj.khem@gmail.com>
-for go 1.10.  Should be applied conditionally on
-musl being the system C library.
-
-Adapted to Go 1.13 from patches originally submitted to
-the meta/recipes-devtools/go tree by
-Matt Madison <matt@madison.systems>.
-
-Upstream-Status: Inappropriate [Real fix should be portable across libcs]
