go 1.9/1.11: fix textrel qa warning for non mips arch

While building go itself, the go build system does not support
to set `-buildmode=pie' from environment.

Add GOBUILDMODE to support it which make PIE executables the default
build mode, as PIE executables are required as of Yocto

But mips doesn't support -buildmode=pie, so skip the QA checking for
mips and its variants
