   LINK  tests/test-coroutine
osdep.o: In function `qemu_close':
osdep.c:(.text+0x4b1): undefined reference to `monitor_fdset_dup_fd_find'
osdep.c:(.text+0x51b): undefined reference to `monitor_fdset_dup_fd_remove'

At least some test executables need libqemustub.a.

I also noted that QEMU tries to build several 32 bit applications for the tests
even on 64 bit hosts. We currently don't check whether the host supports
32 bit builds. Here a check in configure should be added. On a Debian host,
I had to install those packages:

2012-11-19 07:24:41 status installed libc6-i386 2.11.3-4
2012-11-19 07:24:41 status installed libc6-dev-i386 2.11.3-4
2012-11-19 07:30:22 status installed lib32gcc1 1:4.4.5-8
2012-11-19 07:30:22 status installed lib32gomp1 4.4.5-8
2012-11-19 07:30:22 status installed gcc-4.4-multilib 4.4.5-8
2012-11-19 07:30:22 status installed gcc-multilib 4:4.4.5-1

'make test' still fails because more 32 bit packages are missing:

gcc -m32  -o test_path test_path.o -lrt -pthread -lgthread-2.0 -lrt -lglib-2.0
/usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.4.5/../../../libgthread-2.0.so when searching for -lgthread-2.0

/usr/bin/ld: cannot find -lgthread-2.0
collect2: ld returned 1 exit status

This needs a configure check, too (or 'make test' should skip that test if there is no 32 bit libgthread-2.0).
