mpc: Update to 0.30. Use autotools

Package versions newer than 0.28 require meson/ninja which OpenWrt does not support in its build environment. These files provide the minimum autotool configuration necessary to build later versions. Signed-off-by: Ted Hess <thess@kitschensync.net>

 # SYNOPSIS
 #
 #   AX_APPEND_COMPILE_FLAGS([FLAG1 FLAG2 ...], [FLAGS-VARIABLE], [EXTRA-FLAGS])
 #
 # DESCRIPTION
 #
 #   For every FLAG1, FLAG2 it is checked whether the compiler works with the
 #   flag.  If it does, the flag is added FLAGS-VARIABLE
 #
 #   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
 #   CFLAGS) is used.  During the check the flag is always added to the
 #   current language's flags.
 #
 #   If EXTRA-FLAGS is defined, it is added to the current language's default
 #   flags (e.g. CFLAGS) when the check is done.  The check is thus made with
 #   the flags: "CFLAGS EXTRA-FLAGS FLAG".  This can for example be used to
 #   force the compiler to issue an error when a bad flag is given.
 #
 #   NOTE: This macro depends on the AX_APPEND_FLAG and
 #   AX_CHECK_COMPILE_FLAG. Please keep this macro in sync with
 #   AX_APPEND_LINK_FLAGS.

 #   AX_APPEND_FLAG(FLAG, [FLAGS-VARIABLE])
 #
 # DESCRIPTION
 #
 #   FLAG is appended to the FLAGS-VARIABLE shell variable, with a space

 #
 #   If FLAGS-VARIABLE is not specified, the current language's flags (e.g.
 #   CFLAGS) is used.  FLAGS-VARIABLE is not changed if it already contains
 #   FLAG.  If FLAGS-VARIABLE is unset in the shell, it is set to exactly
 #   FLAG.

 # SYNOPSIS
 #
 #   AX_REQUIRE_DEFINED(MACRO)
 #
 # DESCRIPTION
 #
 #   AX_REQUIRE_DEFINED is a simple helper for making sure other macros have
 #   been defined and thus are available for use.  This avoids random issues
 #   where a macro isn't expanded.  Instead the configure script emits a
 #   non-fatal:
 #
 #     ./configure: line 1673: AX_CFLAGS_WARN_ALL: command not found
 #
 #   It's like AC_REQUIRE except it doesn't expand the required macro.
 #
 #   Here's an example:
 #
 #     AX_REQUIRE_DEFINED([AX_CHECK_LINK_FLAG])
