[ptxdist] OSELAS toolchain and real host side libisl bug while compiling host-cloog

[Alexander Aring]

Hi,

I helped somebody which had a host side libisl and he got a compile failure:

libtool: link: ranlib .libs/libcloog-isl.a
libtool: link: ( cd ".libs" && rm -f "libcloog-isl.la" && ln -s "../libcloog-isl.la" "libcloog-isl.la" )

while compiling host-cloog.

The issue is that cloog use the REAL host side libisl, etc. I fixed it in rules/host-cloog.make with the
additional configure argument:

--with-isl-prefix=$(PTXCONF_SYSROOT_HOST) \

additional we need also the same for libgmp:

--with-gmp-prefix=$(PTXCONF_SYSROOT_HOST) \

Maybe something for the next OSELAS release.
