[PATCH v2 4/6] lib/oe/utils.py: add get_host_compiler_version()

Tim Orling
2020-03-31T20:03:28Z

Add helper function to get the host compiler and version.
Do not assume compiler is gcc.

NOTE: cannot set env to d.getVar("PATH") as that does not contain
the session PATH which was set by environment-setup-... which
breaks the install-buildtools use-case
