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

Patch that fixes the problem reported by Christian Borntraeger.
The problem was created by keeping the shared memory mapped file opened
without reason till the process does an exec.
In case of a chain of forked processes (without exec), the range of safe_fd
reserved for Valgrind own usage becomes exhausted.
* coregrind/m_gdbserver/remote-utils.c :
do not VG_(safe_fd) shared_mem_fd (as it is now closed directly)
close shared_mem_fd once file is mmap-ed and written.
* gdbserver_tests/nlfork_chain.stderr.exp,nlfork_chain.vgtest,
fork_chain.c,nlfork_chain.stdout.exp:
new files
* gdbserver_tests/Makefile.am:
modified for new nlfork_chain test
