# Build go programs

# prerequisites:
# - cross/module depends on native/go only
# - module does not require kernel (REQUIRE_KERNEL)
# 
# remarks:
# - Restriction for minimal DSM version is not supported (toolchains are not used for go builds)
# - CONFIGURE_TARGET is not supported/bypassed
# - most content is taken from spksrc.cc.mk and modified for go build and install
