| # 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/ |
