This patch to libgo aligns the variable work in mgc0.c on an 8-byte
boundary. The code expects that to be the case, and complains if it is
not aligned. It would already be the case on a 64-bit system, but not
necessarily on a 32-bit system. I haven't been able to recreate PR
59866, but I think this will fix it. Bootstrapped and ran Go testsuite
on x86_64-unknown-linux-gnu. Committed to 4.8 branch and mainline.
Ian
