This integrates Jan Kratochvil's nice race reproducer from PR testsuite/12649 into the testsuite infrustructure directly. With this, one only has to do either 'make check-read1' or 'make check READ1="1"' to preload the read1.so library into expect. Currently only enabled for glibc/GNU systems, and if build==host==target. gdb/testsuite/ChangeLog: * Makefile.in (EXTRA_RULES, CC): New variables, get from configure. (EXPECT): Handle READ1 being set. (all): Depend on EXTRA_RULES. (check-read1, expect-read1, read1.so, read1): New rules. * README (Testsuite Parameters): Document the READ1 make variable. (Race detection): New section. * configure: Regenerate. * configure.ac: If build==host==target, and running under a GNU/glibc system, add read1 to the extra Makefile rules. (EXTRA_RULES): AC_SUBST it. * lib/read1.c: New file. gdb/ChangeLog: * Makefile.in (check-read1): New rule.
