* paread.c (pa_symtab_read): Update the "check_strange_names"
        filter to match GCC's current output.  Filter out section symbols
        (which the HP linker sometimes puts in the wrong place).

/* GAS leaves labels in .o files after assembling. At
least labels starting with "LS$", "LBB$", "LBE$",
"LC$", and "L$" can happen. This should be fixed in
the assembler and/or compiler, to save space in the
executable (and because having GDB make gross
distinctions based on the name is kind of ugly), but
until then, just ignore them. ("L$" at least, has something
to do with getting relocation correct, so that one might
be hard to fix). */

only filter out L$ symbols which are left in due to
limitations in how GAS generates SOM relocations.
When linking in the HPUX C-library the HP linker has
the nasty habit of placing section symbols from the literal
subspaces in the middle of the program's text. Filter
those out as best we can. Check for first and last character
