    gnu: linux: Allow kconfig options to be strings
    
    * gnu/packages/linux.scm (config->string): add a clause handling strings
    
    Allows for the declarative configuration of kconfig options which accept
    strings, such as CONFIG_MODULE_SIG_KEY.
    
    I've enclosed the given string in quotes, but don't do any kind of
    escaping. See the kernel mailing list for the current state of escaped
    strings upstream:
    
    
https://patchwork.kernel.org/project/linux-kbuild/patch/1431003982-992-1-git-send-email-sr@denx.de/
    
    Apologies to those with double-quotes or backslashes in their
    CONFIG_SYSTEM_*_KEYS.
