The mktables binary needs to be build with the host

it runs at build time to generate the raid tables.
Copy auto-fu from xfsprogs and modify Makefile to
accomodate this.

Looks better than my previous patch.
With @BUILD_CLFAGS support and better BUILD_CC/CLFAGS detection for
native build environment.
The contents of tables.c has practially not changed since its
introduction in 2000s. I see no sense in regenerating it each time
during build and I don't want to introduce host CC build just for
this one file, standard practice or not.
I understand the worry about adding host CC.
But just shown by the patch, the impact is minimal.
At least for me and already mentioned before, text file managed by git
should be reviewable.
No matter if the file get modified in 20 years or not.
(BTW, I don't think there is much problem regenerating the RAID6 table.
It's way faster than auto-conf/auto-header things)
And I think that's the same reason other projects doesn't manage their
generated CRC tables using git.
Thanks,
Qu
