# 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/
