package/go: Add HOST_GO_CGO_ENABLED
The go compiler's cgo support uses threads. If BR2_TOOLCHAIN_HAS_THREADS is
set, build in cgo support for any go programs that may need it. Note that
any target package needing cgo support must include
'depends on BR2_TOOLCHAIN_HAS_THREADS' in its config file.
Fixes build errors like these:
error: #warning requested reentrant code
