Since -r in GCC 6/7/8 doesn't imply -nostdlib -nostartfiles, update the link-static-libc.out rule to also pass -nostdlib -nostartfiles. This fixes BZ #31753. Signed-off-by: H.J. Lu <hjl.tools@gmail.com> Reviewed-by: Florian Weimer <fweimer@redhat.com>

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.
