Grub cannot run two platforms at the same time, so there is no need to have second one.

I do not use VB, I use QEMU.

If you check my last comment you will see that my commands make sure that I do not have any grub2 package installed.

If you know how to build both pc and efi platforms in the same command so that I can use your proposed command to avoid having to install grub2 with make install into my chroot that would be nice.

What Virtualbox version are you using?

I can't reproduce it using current git. Your command grub-mkrescue does not use build directory so you are using some grub version provided by your distribution. To create rescue CD from just compiled grub use

pkgdatadir=$PWD ./grub-mkrescue -d grub-core -o /tmp/test1.iso

from build directory after make has completed.
