[Differential] [Commented On] D2005: Start of arm64 toolchain support (sufficient for kernel-toolchain)

[emaste (Ed Maste)]

emaste added a comment.

Perhaps something like
```
-.if defined(WITHOUT_${var})                    # WITHOUT always wins
+# WITHOUT and __FORCE_NO always win
+.if defined(WITHOUT_${var}) || defined(__FORCE_NO_${var}
```
along with
```
+__FORCE_NO_GDB=true
+__FORCE_NO_BINUTILS=true
+__FORCE_NO_BINUTILS_BOOTSTRAP=true
```
for arm64
