[0/2] selftests: sgx: Fix build of test_sgx

Message

CC can have multiple sub-strings like "ccache gcc". Build system of sgx
selftest is unable to support this use case and test_sgx isn't built.
Then rsync gives an erorr:

rsync: [sender] link_stat "//linux/build/kselftest/sgx/test_sgx" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1333) [sender=3.2.3]

This can be fixed if CC is considered to have one string while passing to
check_cc.sh script and inside this script, CC is expanded before execution.

Following build tests have been performed to confirm that these patches
don't break anything else. The verification has also been done through
KernelCI scripts locally as KernelCI has caught this bug:
1) cd tools/testing/selftests && make
2) make -C tools/testing/selftests
3) make -C tools/testing/selftests O=build
4) make -C tools/testing/selftests O=build CC="ccache gcc"
5) ./kci_build make_kselftest

  selftests: x86: allow expansion of $(CC)
  selftests: sgx: Treat CC as one argument
