I started with all options off and then enabled them one by one
until it built, looking at the failures to figure out which
option might be responsible.   OPTION_EGLIBC_RTLD_DEBUG was
the first one, which depends on OPTION_POSIX_WIDE_CHAR_DEVICE_IO
which in turn depends on OPTION_POSIX_C_LANG_WIDE_CHAR.
OPTION_EGLIBC_NSSWITCH and OPTION_EGLIBC_INET were next.
OPTION_EGLIBC_LIBM is needed by gcc (eglibc itself builz
without it).
