The patch titled
     Subject: arch/x86/Makefile: use $(CONFIG_SHELL)

Subject: arch/x86/Makefile: use $(CONFIG_SHELL)

When scripts/x86-check-compiler.sh doesn't have the x bit set:

q:/usr/src/25> make clean
make: execvp: ./scripts/x86-check-compiler.sh: Permission denied

Fix this by using $(CONFIG_SHELL).

This will happen if the user downloads and applies patch-5.7.tar.gz, since
patch(1) doesn't preserve the x bit.
