S390: Use compile-only instead of also link-tests in configure.
Some of the s390-specific configure checks are using compile and link configure tests. Now use only compile tests as the link tests fails when e.g. bootstrapping a cross-toolchain due to missing crt-files/libc.so. This is achieved by using AC_COMPILE_IFELSE in configure.ac file. This is observable e.g. when using buildroot which builds glibc only once or the build-many-glibcs.py script. Note that the latter one is building glibc twice in the compilers-step (configure-checks fails) and in the glibcs-step (configure-checks succeed). Note, that the s390 specific configure tests for static PIE have to link an executable to test binutils support. Thus we can't fix those tests.
