References: https://stackoverflow.com/a/49868387 https://sourceware.org/bugzilla/show_bug.cgi?id=11420 Configure uses "gcc -o conftest -g ... conftest.c -ldl -lncurses -lm -ldl ... -lpthread ... -lpython2.7" when deciding whether give libpython is usable. That of course is the wrong link order, and only works for shared libraries (mostly by accident), and only on some systems. gdb/ChangeLog: PR gdb/11420 * configure.ac: Prepend libpython. * python/python-config.py: Likewise. * configure: Regenerate.
