The current list of exported functions lacks quite a few bog-standard C
library functions that we might as well expose, since U-Boot certainly
has them implemented anyway. There's no reason a standalone
application should have its own strlen() implementation or link in a
copy from some tiny libc.
For a customer's standalone app, this means it goes from 95K to 10K.
More importantly, we can ditch the custom toolchain including a
newlibc used to build the standalone app and just use the same
toolchain as used to build u-boot itself.
