[gdb/testsuite] Allow some tests in gdb.base/restore.exp to be unsupported
We currently run into:
...
248 n = callee1 (n + l5);
(gdb) PASS: gdb.base/restore.exp: caller5 calls callee1; return callee now
print l1
$51 = <optimized out>
(gdb) FAIL: gdb.base/restore.exp: caller5 calls callee1; return restored l1 \
to 32492
...
The problem is that we try to access the value of l1 in function caller5, but
variable l1 has no DW_AT_location attribute. Since l1 is declared using the
register keyword, it's valid for gcc to emit no DW_AT_location at -O0.
Change the FAIL into an UNSUPPORTED.
Tested on x86_64-linux.

2019-09-22 Tom de Vries <tdevries@suse.de>
* gdb.base/restore.exp: Allow register variables to be optimized out at
-O0.
