# Here's how the cross-compile logic breaks down ...
#  CTARGET - machine that will target the binaries
#  CHOST   - machine that will host the binaries
#  CBUILD  - machine that will build the binaries
# If CTARGET != CHOST, it means you want a libc for cross-compiling.
# If CHOST != CBUILD, it means you want to cross-compile the libc.
#  CBUILD = CHOST = CTARGET    - native build/install
#  CBUILD != (CHOST = CTARGET) - cross-compile a native build
#  (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/
