[Bug 56279] Wine fails to build if CC is set to the absolute path for the compiler

[WineHQ Bugzilla]

--- Comment #2 from Vibhav Pant  ---
The issue seems to be due to the configure script deriving the target string
from CC by chopping off the -gcc/-clang prefix, which works if CC only contains
the executable name:

I have created an MR to fix this:
