Kbuild: Ignore GREP_OPTIONS env variable
When building the kernel in a shell which defines GREP_OPTIONS so that grep behavior is modified, we can break the generation of the syscalls table like so: __SYSCALL_COMMON(^[[01;31m^[[K0^[[m^[[K, sys_read, sys_read) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K, sys_write, sys_write) __SYSCALL_COMMON(^[[01;31m^[[K1^[[m^[[K0, sys_mprotect, sys_mprotect) ... This is just the initial breakage, later we barf when generating modules. In this case, GREP_OPTIONS contains "--color=always" which adds the shell colors markup and completely fudges the headers under ...generated/asm/. Fix that by unexporting the GREP_OPTIONS variable for the whole kernel build as we tend to use grep at a bunch of places.
