Hello,

galaxy-2.2 suffers from underlinking with -lpthread:

i686-pc-linux-gnu-g++ -march=native -m32 -O2 -funswitch-loops -fpredictive-commoning -Wl,-O1,--as-needed -pipe galaxy.o zfuncs.o `pkg-config --libs gtk+-3.0` -o galaxy       
/usr/lib/gcc/i686-pc-linux-gnu/4.7.3/../../../../i686-pc-linux-gnu/bin/ld: zfuncs.o: undefined reference to symbol 'pthread_create@@GLIBC_2.1'

Can be fixed by adding -lpthread to the compilation command.

galaxy-2.2-pthread.patch

Fix underlinking with pthread. This also moves pthread CFLAGS modification from ebuild to Makefie patch, because we need to patch anyway.

Apply patch and remove flags mangling because it is moved to the ebuild.
