libelf still doesn't work with GCC. All testsuite failures
are of the form
collect2: lto-wrapper returned 1 exit status
compiler exited with status 1
output is:
lto1: error: could not open ELF file: Request error: invalid ELF_C_* argument
lto-wrapper: /usr/home/sgk/gcc/obj4x/gcc/testsuite/gfortran/../../gfortran returned 1 exit status
collect2: lto-wrapper returned 1 exit status
