[PATCH] bin/stdc: Case-insensitive standard

[Oskari Pirhonen <xxc3ncoredxx@xxxxxxxxx>]

Perform a case-insensitive match on the standard given on the cli so
that the following works as expected:

    $ stdc c89 printf
             int printf(const char *format, ...);
    $ stdc C89 printf
             int printf(const char *format, ...);
