It means that your C compiler - here mpicc - is not properly invoked or
produces broken executables ... And the "see config.log" is the right
suggestion.  Look for failed tests - conftests- outputs in that file to
understand what happens. And maybe show us the relevant part for more
specific replies.

openmpi-1.2.7 should work but a bit oldish. Abinit will probably not
compile "as-is" with the stock Centos 5 openmpi/gcc - gcc-4.1.2 is too
old and buggy. My suggestion is to build your own compiler toolchain - a
gcc/gfortran-4.3.4 and openmpi-1.3.1 - before trying to compile abinit.
Maybe show us the output of mpif90 -showme, mpicc -showme, gfortran -v,
... . Check with "which gfortran" "which mpif90" ... that the right
compilers are in the PATH

Kind regards,

Alain
