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.

Description: Handle unaligned buffers in connect's TYPBLK class
On MIPS platforms (and probably others) unaligned memory access results in a
bus error. In the connect storage engine, block data for some data formats is
stored packed in memory and the TYPBLK class is used to read values from it.
Since TYPBLK does not have special handling for this packed memory, it can
quite easily result in unaligned memory accesses.
.
The simple way to fix this is to perform all accesses to the main buffer
through memcpy. With GCC and optimizations turned on, this call to memcpy is
completely optimized away on architectures where unaligned accesses are ok
(like x86).

Description: Fix DEFAULT_MACHINE on mips
The DEFAULT_MACHINE constant is calculated from the CMAKE_SYSTEM_PROCESSOR
variable which contains the processor which built mariadb. Since most Debian
buildds run on 64-bit hardware even though they build 32-bit binaries,
DEFAULT_MACHINE previously contained "mips64" on 32-bit builds. This confuses
some mroonga tests which rely on DEFAULT_MACHINE to detect 64-bitness.
.
This patch fixes the value of DEFAULT_MACHINE so it always contains just "mips"
on 32-bit mips builds.

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].
