build: Build and check (ice-9 popen) only when --enable-posix and HAVE_FORK.
Fixes <http://bugs.gnu.org/13848>. Reported by Jan Schukat <shookie@email.de>. * configure.ac: Rename `HAVE_FORK' conditional to `BUILD_ICE_9_POPEN'. Set it when both $enable_posix and $ac_cv_func_fork are true. * libguile/posix.c (scm_init_posix): Add the `fork' feature. * doc/ref/api-options.texi (Common Feature Symbols): Add `fork'. * doc/ref/posix.texi (Pipes): Add footnote mentioning the `fork' feature. * module/Makefile.am (SCRIPTS_SOURCES): Make `scripts/autofrisk.scm' and `scripts/scan-api.scm' conditional on `BUILD_ICE_9_POPEN'. * test-suite/tests/popen.test (if-supported): New macro. Wrap body in `if-supported'.
