ARC: build: Try to guess GCC variant of cross compiler
[ Upstream commit 824927e88456331c7a999fdf5d9d27923b619590 ]
ARC GCC compiler is packaged starting from Fedora 39i and the GCC
variant of cross compile tools has arc-linux-gnu- prefix and not
arc-linux-. This is causing that CROSS_COMPILE variable is left unset.
This change allows builds without need to supply CROSS_COMPILE argument
if distro package is used.
Before this change:
$ make -j 128 ARCH=arc W=1 drivers/infiniband/hw/mlx4/
gcc: warning: ‘-mcpu=’ is deprecated; use ‘-mtune=’ or ‘-march=’ instead
gcc: error: unrecognized command-line option ‘-mmedium-calls’
gcc: error: unrecognized command-line option ‘-mlock’
gcc: error: unrecognized command-line option ‘-munaligned-access’
