[gdb/testsuite] Allow args in gdb_caching_proc
Test-case gdb.base/morestack.exp contains:
...
require {have_compile_flag -fsplit-stack}
...
and I want to cache the result of have_compile_flag.
Currently gdb_caching_proc doesn't allow args, so I could add:
...
gdb_caching_proc have_compile_flag_fsplit_stack {
return [have_compile_flag -fsplit-stack]
}
...
and then use that proc instead, but I find this cumbersome and
maintenance-unfriendly.
Instead, allow args in a gdb_caching_proc, such that I can simply do:
...
-proc have_compile_flag { flag } {
+gdb_caching_proc have_compile_flag { flag } {
...
Note that gdb_caching_procs with args do not work with the
gdb.base/gdb-caching-procs.exp test-case, so those procs are skipped.
Tested on x86_64-linux.
