After the move to CLooG 0.17.0/ISL 0.10, mainline fails to configure
with a static libisl:
configure:5697: checking for version 0.10 of ISL
configure:5722: gcc -o conftest -g -O2 -I/vol/gcc/include -I/vol/gcc/include -I/
vol/gcc/include -I/vol/gcc/include -L/vol/gcc/lib -lisl -lisl conftest.c >&5
Undefined first referenced
symbol in file
isl_version /var/tmp//ccKVG1Pf.o
ld: fatal: symbol referencing errors. No output written to conftest
In the static case, -lisl needs to be added after conftest.c, not
before. The following patch does just that by moving -lisl to LIBS.
It allowed a i386-pc-solaris2.10 bootstrap to finish without
regressions.
Ok for mainline?

toplevel:
* configure: Regenerate.
config:
* isl.m4 (ISL_CHECK_VERSION): Add -lisl to LIBS, not LDFLAGS.
