Subject: [PATCH] Revert "cmd/go: make sure CC and CXX are absolute"

OE uses CC/CXX values which consists of cmpiler and options together,
secondly, the environment is canned so this check add little value to OE
based builds

Fixes go-runtime build issues

go install: CXX environment variable is relative; must be absolute path: powerpc64le-yoe-linux-musl-g++ -mlittle-endian -mhard-float -m64 -mabi=elfv2 -mcpu=power9 -fstack-protector-strong -O2 -D_FORTIFY_SOURCE=2 -Wformat -Wformat-security -Werror=format-security --sysroot=/mnt/b/yoe/master/build/tmp/work/ppc64p9le-yoe-linux-musl/go/1.16-r0/recipe-sysroot

This reverts commit aa161e799df7e1eba99d2be10271e76b6f758142.
