The 30379efad1 added _FORTIFY_SOURCE checks without check if compiler
does support all used fortify levels. This patch fixes it by first
checking at configure time the maximum support fortify level and using
it instead of a pre-defined one.
Checked on x86_64 with gcc 11, 12, and 13.

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.
