A minor change to ROMIO's configure script: make it use exactly the

same "restrict" check as the top-level OMPI configure.ac script so
that it will guarantee to always get the same result.  Therefore, the
#define for restrict will always have the same value in both
opal_config.h and romioconf.h, and we get 7 less warnings (6 in the IO
ROMIO component, 1 in ROMIO itself) when compiling with icc on Linux
(because PAC_C_RESTRICT and AC_C_RESTRICT would get different values
for the "restrict" #define in this case).

This commit was SVN r14387.
