I had a go at this. Fewer recipes than I expected seem to be affected.

With bitbake.conf containing EXTRA_OEMAKE = "", the following recipes
needed to be changed to explicitly set EXTRA_OEMAKE = "-e MAKEFLAGS=":

 meta/recipes-bsp/pciutils/pciutils_3.3.1.bb
 meta/recipes-connectivity/openssl/openssl.inc
 meta/recipes-core/busybox/busybox.inc
 meta/recipes-devtools/perl/perl_5.22.0.bb

for core-image-minimal to build successfully[1].

I tried core-image-sato but got stuck when apr-util-native wouldn't compile
for me[2], even with stock master.

So, perhaps the situation isn't quite as bad as I feared and it might be
possible to change the default value of EXTRA_OEMAKE.

[1] I suspect that perl isn't required by core-image-minimal. That list is
    my complete set of changes from trying to get core-image-sato to build.
