+gccgo setcontext conftest crashes qemu-sh4

+While testing gccgo on sh4 to add SH platform definitions to libgo, I discovered that the following conftest program which is part of the libgo configure script crashes on qemu-sh4:

+The same code works fine on my Renesas SH7785LCR evaluation board:

+Due to this bug, it is not possible to compile gcc-7 with the Go frontend enabled on qemu-sh4.
