[libvirt] [PATCH] compile: fix undefined reference to gnutls_x509_crt_get_dn with gcc-4.6.1



From: soulxu <soulxu soulxu-ThinkPad-T410 (none)>

When I compile libvirt with gcc-4.6.1 in ubuntu 11.10, got error as below:

  CCLD   libvirtd
/usr/bin/ld: ../src/.libs/libvirt_driver_qemu.a(libvirt_driver_qemu_la-qemu_migration.o): undefined reference to symbol 'gnutls_x509_crt_get_dn@@GNUTLS_1_4'
/usr/bin/ld: note: 'gnutls_x509_crt_get_dn@@GNUTLS_1_4' is defined in DSO /usr/lib/x86_64-linux-gnu/libgnutls.so so try adding it to the linker command line
/usr/lib/x86_64-linux-gnu/libgnutls.so: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [libvirtd] Error 1


It can compile with gcc-4.5.2 in ubuntu 11.04, but it can not compile with gcc-4.6.1 in ubuntu 11.10.

I didn't find reason. Does Anyone know the reason or the different between gcc-4.5.2 and gcc-4.6.1?

I still provide a patch for this. Just make it is working now.
