[dpdk-dev] [PATCH 1/2] mk: overriding CC also overrides HOSTCC

[Bruce Richardson]

when overriding the CC variable on the commandline, the HOSTCC value
was remaining at "gcc", which caused errors on Free BSD10 when using a gcc
as e.g. gcc48, without a binary just called "gcc". This change overrides
HOSTCC when CC is overridden, which means that setting CC=gcc48, will
now also set HOSTCC=gcc48, allowing the "testhost" app to compile on BSD10
