krb5-config tells the application programmer what
  special flags to use to compile and link programs against the libraries
  installed by Heimdal.
Options supported:
  - -- -prefix[=dir]
- Print the prefix if no dir is specified, otherwise
      set prefix to dir.
- -- -exec-prefix[=dir]
- Print the exec-prefix if no dir is specified,
      otherwise set exec-prefix to dir.
- -- -libs
- Output the set of libraries that should be linked against. This also
      includes rpath flags with the expectation that the C compiler is used for
      final link-edits.
- -- -cflags
- Output the set of flags to give to the C compiler when using the Heimdal
      libraries.
By default krb5-config will output the set
    of flags and libraries to be used by a normal program using the krb5 API.
    The user can also supply a library to be used, the supported ones are:
  - krb5
- (the default)
- gssapi
- use the krb5 gssapi mechanism
- kadm-client
- use the client-side kadmin libraries
- kadm-server
- use the server-side kadmin libraries
