[Buildroot] [PATCH v3, 2/2] package/mpd: fix static build with tremor and vorbis

[Fabrice Fontaine]

mpd can't be built statically with tremor and vorbis, build fails on:
block.c:(.text+0x11c): multiple definition of `vorbis_block_init'
/usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/bin/../sparc-buildroot-linux-uclibc/sysroot/usr/lib/libvorbisidec.a(block.o):block.c:(.text+0x0): first defined here
/usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/opt/ext-toolchain/bin/../lib/gcc/sparc-buildroot-linux-uclibc/7.4.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: Disabling relaxation: it will not work with multiple definitions
/usr/lfs/v0/rc-buildroot-test/scripts/instance-2/output/host/bin/../sparc-buildroot-linux-uclibc/sysroot/usr/lib/libvorbis.a(block.o): In function `_vorbis_block_alloc':

Fix this by making both options mutually exclusive

It should be noted that upstream removed the possibility to enable
tremor and vorbis at the same time since version 0.21.6 and
https://github.com/MusicPlayerDaemon/MPD/commit/c18cd941aaa4c16ac713bc4f1e16ada5281d689e

Changes v2 -> v3 (after review of Thomas Petazzoni):
 - Move drop of tremor select in a dedicated patch
 - Remove BR2_SOFT_FLOAT dependency and make both options mutually
   exclusive

Changes v1 -> v2 (after review of Thomas Petazzoni):
 - Drop default and replace it by a dependency on BR2_SOFT_FLOAT or
   !BR2_SOFT_FLOAT
