[Xcb] profiling option for xcb

[Vincent Torri]

Hello,

I have added a profile option for configure, so that we can use gprof if
we want to profile an xcb program.

patched attached for configure.ac and Makefile.am

is it worth a commit ? (also, if you want me to change the names of the
variables, please tell me)

Vincent
