Subject: [PATCH v1] kbuild: Disable compile testing if HAVE_LEGACY_CLK enabled

There are couple older platforms that can't be compile-tested because they
partially implement CLK API. It causes build failure of kernel drivers due
to the missing symbols of the unimplemented part of CLK API.

These platforms are: ARM EP93XX, ARM OMAP1, m68k ColdFire, MIPS AR7,
                     MIPS Ralink.

Disable compile-testing for HAVE_LEGACY_CLK=y.
