MDEV-23618 InnoDB lacks IA-32 CRC-32C acceleration on GCC 4
When MDEV-22669 introduced CRC-32C acceleration to IA-32,
it worked around a compiler bug by disabling the acceleration
on GCC 4 for IA-32 altogether, even though the compiler bug
only affects -fPIC builds that are targeting IA-32.
Let us extend the solution fe5dbfe723427a3606c41409626dc853f997e679
and define HAVE_CPUID_INSTRUCTION that allows us to implement
a necessary and sufficient work-around of the compiler bug.
