PR 54918 points out that libgo is not using version numbers as it should. At present none of libgo in 4.6, 4.7 and mainline are compatible with each other. This patch to the 4.7 branch sets the version number for libgo there. Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu. Committed to 4.7 branch.
