package/go: needs PIE support
When built statically, runc try to link against Scrt1.o which is not
provided by uClibc ARM toolchain for static build only.
[...]arm-buildroot-linux-uclibcgnueabi/bin/ld: cannot find Scrt1.o: No such file or directory
collect2: error: ld returned 1 exit status
On ARM, Go forces the use of -pie, for some reason:
pie := (goarch == "arm" && goos == "linux") || goos == "android"
if pie { // we need to use -pie for Linux/ARM to get accurate imported sym
cgoLDFLAGS = append(cgoLDFLAGS, "-pie")
}
For this reason, add a dependency on BR2_TOOLCHAIN_SUPPORTS_PIE for ARM
CPUs to disable Go for such toolchains.
While at it, rewrap Go dependencies.
