    [gdb/testsuite] Fix gdb.base/msym-lang.exp on ppc64-linux
   =20
    On x86_64-linux, with test-case gdb.base/msym-lang.exp we get:
    ...
    (gdb) info func foo
    All functions matching regular expression "foo":
   =20
    Non-debugging symbols:
    0x0000000000401116  foo()
    0x000000000040112c  foo()
    (gdb) PASS: $exp: info func foo
    ...
   =20
    But on ppc64-linux, we get:
    ...
    (gdb) info func foo
    All functions matching regular expression "foo":
   =20
    Non-debugging symbols:
    0x0000000000000914  .foo()
    0x0000000000000974  .foo()
    (gdb) FAIL: $exp: info func foo
    ...
   =20
    The dot prefix is due to the function descriptors used in the PPC v1 AB=
I.
   =20
    Fix this by allowing the dot prefix.
   =20
    Tested on x86_64-linux and ppc64-linux.
