Subject: Improve default HOST_CC / CC settings
X-Git-Tag: v3.3.0~83
X-Git-Url: http://zhaoyanbai.com/repos/Bv9ARM.ch13.html?a=commitdiff_plain;h=f1deff716ea30b28693c16f8e48ba1a369e2e922;p=minix.git

Improve default HOST_CC / CC settings

Instead of blindly defaulting to cc, try to find the actual compiler
installed on the system, and as a last resort
