+Subject: [PATCH] gotools: fix compilation when making cross compiler
+
+libgo is "the runtime support library for the Go programming language.
+This library is intended for use with the Go frontend."
+
+gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
+the linker will complain that it cannot find it. That's because shared libgcc
+is not present in the install directory yet. libgo.so was made without problem
+because gcc will emit -lgcc_s when compiled with -shared option. When gotools
+were being made, it was supplied with -static-libgcc thus no link option was
+provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
+for linking with libgo.so
+
+- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
+- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
+
+When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
+available after gcc pass2 completed and will meet the gotools link requirement
+at gcc pass3
