building clang and/or gcc as the bootstrap compiler. Normally, the default compiler is used. WITH_CLANG_BOOTSTRAP and/or WITH_GCC_BOOTSTRAP will enable building these compilers as part bootstrap phase. WITH/WITHOUT_CLANG_IS_CC controls which compiler is used by default for the bootstrap phase, as well as which compiler is installed as cc. buildworld now successfully completes building the cross compiler with WITHOUT_CLANG=t and WITHOUT_GCC=t and produces a built system with neither of these included. Similarlly, MK_BINUTILS_BOOTSTRAP controls whether binutils is built during this phase. WITHOUT_CROSS_COMPILER will now force MK_BINUTILS_BOOTSTRAP=no, MK_CLANG_BOOTSTRAP=no and MK_GCC_BOOTSTRAP=no. BOOTSTRAP_COMPILER was considered, but rejected, since pc98 needs both clang and gcc to bootstrap still. It should be revisisted in the future if this requirement goes away. Values should be gcc, clang or none. It could also be a list. The odd interaction with Xfoo cross/external tools needs work, but is beyond the scope of this change as well.

Set to not build any cross compiler in the cross-tools stage of buildworld.
|
|
If you are compiling a different version of
|
|
.Fx
|
|
than what is installed on the system, you will need to provide an alternate
|
|
compiler with XCC to ensure success.
|
|
If you are compiling with an identical version of
|
|
.Fx
|
|
to the host, this option may be safely used.
|
|
This option may also be safe when the host version of
|
|
.Fx
|
|
is close to the sources being built, but all bets are off if there have
|
|
been any changes to the toolchain between the versions.
