i do a separate isl build so no, haven't noticed it

cross phase

isl-0.11.2 LDFLAGS="-Wl,-rpath,/cross-tools/lib" ./configure 
--prefix=/cross-tools --with-gmp-prefix=/cross-tools
cloog-0.18.0, LDFLAGS="-Wl,-rpath,/cross-tools/lib"      ./configure 
--prefix=/cross-tools --with-isl=system --with-gmp=system 
--with-gmp-prefix=/cross-tools --with-isl-prefix=/cross-tools


temp phase


CC="${CC} ${BUILD64}" ./configure --prefix=/tools --build=${CLFS_HOST} 
--host=${CLFS_TARGET} --with-gmp-prefix=/tools

and then cloog

  CC="${CC} ${BUILD64}" ./configure --prefix=/tools --build=${CLFS_HOST} 
--host=${CLFS_TARGET}  --enable-shared --with-isl=system 
--with-gmp=system --with-gmp-prefix=/tools --with-isl-prefix=/tools
