Add a test to check for duplicate definitions in the static library
This change follows two previous fixes addressing multiple definitions
of __memcpy_chk and __mempcpy_chk functions on i586, and __memmove_chk
and __memset_chk functions on i686.  The test is intended to prevent
such issues from occurring in the future.

where <program> is the path to the program being tested,

Options:
-h, --help
Prints this message and leaves.
The following options require one argument:
-b, --breakpoint
Breakpoints to set at the beginning of the execution
(each breakpoint demands its own -b option, e.g. -b foo -b bar)
-e, --environment-variable
Environment variables to be set with 'exec-wrapper env' in GDB
(each environment variable demands its own -e option, e.g.
-e FOO=foo -e BAR=bar)
The following options do not take arguments:
-c, --in-container
Run the test case inside a container and automatically attach
GDB to it.
-i, --no-direct
Selects whether to pass the --direct flag to the program.
--direct is useful when debugging glibc test cases. It inhibits the
tests from forking and executing in a subprocess.
Default behaviour is to pass the --direct flag, except when the
program is run with user specified arguments using the "--" separator.
-s, --no-symbols-file
Do not tell GDB to load debug symbols from the program.
