Check if SBC_BUILD_WITH_MMX_SUPPORT is defined otherwise
sbc_init_primitives_mmx will not be declared and
_builtin_cpu_supports(“mmx”)) likely fail:

sbc: Add sbc_reinit_msbc2020-12-03T13:25:06ZPali Rohárpali@kernel.org2020-11-23T00:01:57Zurn:sha1:10310fb983b0fced7db7bdb2d14ec03c252f8a88
This adds a new API function sbc_reinit_msbc. Like sbc_reinit or
sbc_reinit_a2dp but for msbc.
