you might also want to delete the "#undef BB_LINUXRC" lines in Config.h and
Config.h.Hurd because BB_LINUXRC is nowhere used anymore.

hmm... i definately got this mistake... i'm looking into it... perhaps
there's something wrong with uClibc putenv...

hmmm... right... currently i'm using execl("/sbin/init", "/linuxrc", NULL);
in my linuxrc. this will make busybox think it is linuxrc
(argv[0]="/linuxrc")...
another workaround may be to check if getpid()<10 or something. not a clean
solution but maybe worth to think about it.
