Does not appear to be:

xen5 xen-unstable.hg # ldd tools/libxc/libxenctrl.so
        linux-vdso.so.1 =>  (0x00007fff594c1000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00007ff09b7f6000)
        libc.so.6 => /lib/libc.so.6 (0x00007ff09b49a000)
        /lib64/ld-linux-x86-64.so.2 (0x00007ff09bc41000)

The gcc line:

gcc -O1 -fno-omit-frame-pointer -fno-optimize-sibling-calls -m64 -g 
-fno-strict-aliasing -std=gnu99 -Wall -Wstrict-prototypes 
-Wno-unused-value -Wdeclaration-after-statement  -D__XEN_TOOLS__ -MMD

-lpthread
Usually when I've run into this in the past it's just been an issue of 
putting them in the correct order, take a look at "Importance of linking 
order" here: http://www.gentoo.org/proj/en/qa/asneeded.xml
I've also attached the full make output from tools/libxc.
