Just tried to compile xenomai for beagle. The command line which you
should have, except for the paths, should be:

libtool: link: /home/gilles/src/xenomai/xenomai-2.5/scripts/wrap-link.sh
arm-none-linux-gnueabi-gcc -mfpu=3Dvfp3 -mfloat-abi=3Dsoftfp -march=3Darm=
v7-a
-g -O2
-Wl,@/home/gilles/files/src/xenomai/xenomai-2.5/src/skins/posix/posix.wra=
ppers
-mfpu=3Dvfp3 -mfloat-abi=3Dsoftfp -march=3Darmv7-a -o .libs/cyclictest
cyclictest-cyclictest.o  ../../skins/posix/.libs/libpthread_rt.so
-lpthread -lrt -Wl,-rpath -Wl,//lib
