[gdb/testsuite] Force DWARF in gdb.pascal

On i686-linux (and likewise arm-linux), I run into:
...
(gdb) file str-chars^M
Reading symbols from str-chars...^M
warning: stabs debug information is not supported.^M
(No debugging symbols found in str-chars)^M
(gdb) delete breakpoints^M
...

Fix this by using fpc option -gw2.

Tested on i686-linux.
