[gdb/guile, c++20] Work around Werror=volatile in libguile.h
When building gdb with -std=c++20, I run into:
...
In file included from /usr/include/guile/2.0/libguile/__scm.h:479,
from /usr/include/guile/2.0/libguile.h:31,
from /data/vries/gdb/src/gdb/guile/guile-internal.h:30,
from /data/vries/gdb/src/gdb/guile/guile.c:37:
/usr/include/guile/2.0/libguile/gc.h: In function ‘scm_unused_struct* \
scm_cell(scm_t_bits, scm_t_bits)’:
/usr/include/guile/2.0/libguile/tags.h:98:63: error: using value of \
assignment with ‘volatile’-qualified left operand is deprecated \
[-Werror=volatile]

| ~~~~~~~~~~~~~~~~~~~^~~~~
...
This was reported upstream [1].
Work around this by using SCM_DEBUG_TYPING_STRICTNESS == 0 instead of the
default SCM_DEBUG_TYPING_STRICTNESS == 1.
Tested on x86_64-linux.
