-# If CHOST != CBUILD, it means you want to cross-compile the libc.

-# (CBUILD = CHOST) != CTARGET - libc for cross-compiler
-# CBUILD != CHOST != CTARGET - cross-compile a libc for a cross-compiler
-# For install paths:
-# CHOST = CTARGET - install into /
-# CHOST != CTARGET - install into /usr/CTARGET/
