Patch that makes print foo() do as much checking as possible in absence of
process

I managed to reproduce in a cross setting.

1.
Use platform openSUSE Tumbleweed x86_64.

2.
Reproducer:
...
cat min.c
long double _Complex
foo ()
{
  return 1.0;
}
...

3.
Use powerpc64le-suse-linux-gcc-12 from package cross-ppc64le-gcc12:
...
$ powerpc64le-suse-linux-gcc-12 min.c -O2 -c -g
...

4.
Note the gnu attributes:
...
$ readelf -a min.o
...
Attribute Section: gnu
File Attributes
  Tag_GNU_Power_ABI_FP: hard float, 128-bit IEEE long double
...

5.
Build gdb with patch, to make print foo() to as much checking as possible in
absence of process.

6.
Reproduce:
...
$ gdb -q -batch min.o -ex "show osabi" -ex "show arch" -ex "print foo()" 
The current OS ABI is "auto" (currently "GNU/Linux").
The default OS ABI is "GNU/Linux".
The target architecture is set to "auto" (currently "powerpc:common64").
warning: No process, proceed with type checking
