mariadb: new package

Browse Source 
MariaDB is a drop-in replacement for MySQL. This commit adds a current
and stable version of MariaDB to the tree.

Quite a few ideas/patches were copied from Alpine Linux, Busybox Buildroot
and Debian.

Subject: [PATCH] Remove dependency on glibc on PPC
Remove dependency on glibc by using gcc builtin function and no glibc
wrappers.
Currently there are no surrogates in musl for:
__ppc_get_timebase()
__ppc_set_ppr_low()
__ppc_set_ppr_med()
however glibc __ppc_get_timebase() is just a wrapper for GCC builtin
__builtin_get_timebase() available since GCC 4.8 [1], so assuming that
aports on ppc64le will never be built using GCC < 4.8 we can just
switch directly to the GCC builtin function.
Also __ppc_set_ppr_{low,med}() are not available on musl but both
are simple glibc wrappers on a single asm instruction, hence there
is no harm in using asm directly instead. Actually, using asm
directly was the first solution adopted in MariaDB [2].
