Subject: Makefile.uk: Use -Wno-cast-function-type for GCC >= 8
X-Git-Tag: RELEASE-0.11.0~3
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=481df35f4982c34419a09b7032f9fe6147ae653b;p=unikraft%2Flibs%2Fmusl.git

Makefile.uk: Use -Wno-cast-function-type for GCC >= 8

The build option `-Wno-cast-function-type`, used in `Makefile.uk` is
available from GCC >= 8. When used in GCC <= 7, it issues a warning.

This commit updates the build flags to enable `-Wno-cast-function-type`
only when using GCC >= 8.
