When trying to build on my Centos 5.5 machine, got below error:
| checking for gtkdoc-mkpdf... no
| checking whether to build gtk-doc documentation... no
| checking for CROCO... yes
| checking if gcc supports "-Wl,-Bsymbolic-functions" flag...
| configure: error: -Bsymbolic requested but not supported by ld. Use --disable-Bsymbolic to disable
| Configure failed. The contents of all config.log files follows to aid debugging

Set --enable-Bsymbolic=auto to disable it when it is not suppported.
