This helped, and allowed me to go much further in my build, but the recipe

CXX_pn-gcc-cross-arm= "${BUILD_CXX}"
CC_pn-gcc-crosssdk-x86_64= "${BUILD_CC}"
CXX_pn-gcc-crosssdk-x86_64= "${BUILD_CXX}"
So apparently, gcc still has some reference to $CC and $CXX hardcoded
somewhere (I think it's in do_configure)
It seems to set $CC in the do_compile correctly, but not in do_configure.
And it never sets $CXX
I tried to understand what the GCC recipe was doing wrong, but I couldn't
find out on first look and it's a really complicated recipe
Could you try adding a do_configure_prepend to gcc-cross.inc that sets
exports those (and extend the do_compile exports) to see if that solves it?
I did the following
diff --git a/meta/recipes-devtools/gcc/gcc-cross.inc
b/meta/recipes-devtools/gcc/gcc-cross.inc

(which I think is what you meant) and it did indeed solve the problem.
