libsdl-mixer: fixed the absence of ogg support(because of a libmikmod issue),bump PR and convert libmikmod staging

When I ran wesnoth 1.8.3 I had no music and similar messages on the console:
  error audio: Could not load music file '/usr/share/wesnoth/data/core/music/breaking_the_chains.ogg': Couldn't read from '/usr/share/wesnoth/data/core/music/breaking_the_chains.ogg'
At first I tought that I missed a dlopend library.
But I did an ldd on libsdl-mixer and compared with the version on my desktop:
 root@htcdream ~ # ldd /usr/lib/libSDL_mixer-1.2.so.0.10.1
 	libSDL-1.2.so.0 => /usr/lib/libSDL-1.2.so.0 (0x400 54000)

Then I looked in the configure log of libsdl-mixer and found that:
 .../sysroots/armv6-novfp-oe-linux-gnueabi/usr/lib/libmikmod.so: undefined reference to `floor'
 collect2: ld returned 1 exit status
 configure:11865: $? = 1
During the detection of libvorbis.

I had no idea on how to fix that,so I asked on irc(#oe on Freenode):
Khem helped me a lot and at some point said(about libmikmod):
 Aug 03 16:57:38 <khem>  add -lm to LDFLAGS
And finally:
 Aug 03 17:35:33 <ensc|w>	GNUtoo|laptop: on first glance, EXTRA_OECONF='-lm' might fix it
 Aug 03 17:35:37 <GNUtoo|laptop>	armv6-novfp-oe-linux-gnueabi/libmikmod-3.2.0-beta2-r1/libmikmod-3.2.0-beta2/libmikmod
 Aug 03 17:35:50 <GNUtoo|laptop>	ensc|w, isn't that risky? but I can try that
 Aug 03 17:36:02 <GNUtoo|laptop>	you mean OEMAKE?
 Aug 03 17:36:11 <ensc|w>	wrong... EXTRA_OECONF='LIBRARY_LIB=-lm'
Thanks a lot for the help

About the PR bump:
 19:59 < khem> you should only bump the pr of the package you are modifying
 19:59 < GNUtoo|htcdream> khem: ok thanks a lot
So I bumped only PR of libmikmod and sdl-mixer
