coreutils: enable /proc/uptime support when cross-compiling

Browse source 
/proc/uptime support can't be detected automatically when cross-compiling, so
it is disabled by default. This causes extremely large uptime values (e.g.
19167 days) on systems without RTCs because the boot time is set to the
epoch.
