Fixes#276987. (Philippe Waroquiers, philippe.waroquiers@skynet.be)
* make_local_links
- disable gdb tests if gdb version < 7
- disable pic tests if gdb version < 7.1
* nlfork_chain test
- reduce chain from 20 to 15 to avoid ENOMEM
on small ARM systems
* main_pic.c
- put break at line 11 rather than main entry, as ARM gdb
does not properly show main args till it has started executing.
* passsigalrm.c
- do not setsa.sa_restorer (obsolete on linux, unknown on darwin)
* mcvabits.vgtest
- make prereq consistent with other tests
* filter_gdb
- upgraded filter to new linenr in clean_after_fork.c
