Cloog make check fails on Centos 7

[Dean Anderson]

The libisl.so.15 library is not found due to some autoconf breakage.  

 ./config.status -V

cloog config.status 0.18.4

configured by /var/efsbuild/oss-libcloog-0.18.4-build002-build/x86-32.rhel.7/rh485/source/cloog-0.18.4/configure, generated by GNU Autoconf 2.69,

  with options "'--prefix=/efs/dist/oss/libcloog/0.18.4-build002/common' '--exec_prefix=/efs/dist/oss/libcloog/0.18.4-build002/.exec/x86-32.rhel.7' 'CC=gcc' 'LDFLAGS=-L/efs/dist/gnu/gmp/6.1.2/.exec/x86-32.rhel.7/lib -Wl,-rpath,/efs/dist/gnu/gmp/6.1.2/.exec/x86-32.rhel.7/lib' 'CPPFLAGS=-I/efs/dist/gnu/gmp/6.1.2/.exec/x86-32.rhel.7/include'"

As near as I can determine, the autoconf generated cloog script doesn’t include isl/.libs in its LD_LIBRARY_PATH to invoke cloog.

Thanks,
