Use gen-libm-test.py to generate ulps table for manual.
This patch extends gen-libm-test.py to generate the ulps table for the manual, so meaning there is only a single ulps file parser needed and another Perl script is eliminated. As with the introduction of gen-libm-test.py, this is designed to generate exactly the same libm-err.texi as libm-err-tab.pl did. (gen-libm-test.py is still shorter in lines than the old gen-libm-test.pl even after this patch.) Note that this introduces a Python dependency for building the manual, which is thus noted in install.texi and NEWS. Tested building html / info / pdf versions of the manual. * math/gen-libm-test.py: Import os. (ALL_FLOATS_MANUAL): New constant. (ALL_FLOATS_SUFFIX): Likewise. (Ulps.all_functions): New function. (real_all_ulps): Likewise. (generate_err_table_sub): Likewise. (generate_err_table): Likewise. (main): Handle -s and -m options. * manual/libm-err-tab.pl: Remove. * manual/Makefile ($(objpfx)stamp-libm-err): Use gen-libm-test.py instead of libm-err-tab.pl. [$(PERL) != no]: Change condition to [$(if $(PYTHON),$(PERL),no) != no]. * manual/install.texi (Tools for Compilation): Document requirement for Python to build manual. * INSTALL: Regenerated.
