[PATCH] lto-plugin.c: c23 compatibility: char * -> const char *

[Filip Kastl]

There are two uses of strrchr with const char * parameters in
lto-plugin.c where the result gets assigned to a non-const char *
variable.

Make the variable const char * so that we don't throw away const-ness.
I've seen clang produce warnings about this when compiling lto-plugin.c.

Regtested and bootstrapped on x86_64 linux.

lto-plugin/ChangeLog:

        * lto-plugin.c (process_symtab): char *s -> const char *s.
        (process_symtab_extension): Ditto.
