Bug ID: 29263
Summary: /usr/bin/ld: warning:
/usr/lib/gcc/hppa-linux-gnu/11/../../../hppa-linux-gnu
/crtn.o: missing .note.GNU-stack section implies
executable stack

/usr/bin/ld: warning:
/usr/lib/gcc/hppa-linux-gnu/11/../../../hppa-linux-gnu/crtn.o: missing
.note.GNU-stack section implies executable stack
/usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future
version of the linker
/usr/bin/ld: warning: a.out has a LOAD segment with RWX permissions
The first warning seems bogus as crtn.o is not an executable file.
On hppa-linux with kernel v5.18 and later, we don't need an executable
stack for signal support but we still need it for gcc nested functions.
As far as I can tell, an executable stack is still the default in glibc
for many targets.
