Hmm...  I find it unlikely that this second failure is in any way
related with VTA, but you could confirm that it isn't setting
BOOT_CFLAGS='-g -O2 -fno-var-tracking-assignments', or say
BOOT_CFLAGS='-g -O2 -fcompare-debug=-gtoggle', then wiping out the
stage2 build and starting over.

Here's the updated patch, that accepts ptr_mode in two other locations
where we used to require Pmode.
