CHOST

The CHOST variable tells the compiler for which platform code should be build for. Unlike the CFLAGS variable, which is used for the optimizations, the CHOST variable is rather fixed and cannot be changed easily.

The profile provides the default CHOST, but it can be changed in the.

The variable is a dash-separated tuple in the form of ARCH-VENDOR-OS-LIBC. ARCH specifies the CPU architecture, VENDOR specifies the hardware platform or vendor, OS is the operating system, and LIBC is the C library to use. Only ARCH is strictly required in all cases, but - for Linux machines at least - it's good practice to specify all four fields. The LIBC field is not supported for Gentoo/FreeBSD, so for these machines it must always be omitted.
