[PATCH v5 01/18] configure, meson: override C compiler for cmake

[Jagannathan Raman <jag.raman@oracle.com>]

The compiler path that cmake gets from meson is corrupted. It results in
the following error:
| -- The C compiler identification is unknown
| CMake Error at CMakeLists.txt:35 (project):
| The CMAKE_C_COMPILER:
| /opt/rh/devtoolset-9/root/bin/cc;-m64;-mcx16
| is not a full path to an existing compiler tool.

Explicitly specify the C compiler for cmake to avoid this error
