I tried building an image for RPi4 after enabling a new option in my .config and found that the build is consistently ending an error. Complete make -j1 v=S build log is here.
An excerpt from the log is below and the error message is suggestive that my build root is out of disk space but that is not the case. I have over 40G free on that file system. I also ran e2fsck on the filesystem and no errors were present. Any thoughts?

EDIT: I just found this thread... is the issue that the IMAGE'S root filesystem is now too small to fit all the packages I want?
I partitioned the uSD card for this RPi4 to have a pretty large data partition after the two that the default image created. Here is the partition table on the device:
Disk /dev/mmcblk0: 14.84 GiB, 15931539456 bytes, 31116288 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x5452574f
Device Boot Start End Sectors Size Id Type
/dev/mmcblk0p1 * 8192 139263 131072 64M c W95 FAT32 (LBA)
/dev/mmcblk0p2 147456 360447 212992 104M 83 Linux
/dev/mmcblk0p3 360448 31116287 30755840 14.7G 83 Linux
Should I simply backup all data on /dev/mmcblk0p3, unmount it, delete it, increase the image size in menuconfig, (say change 104 to 256), build and flash that new image, then recreate the data partition and restore the data?
Will this take automatically take care of repartitioning my /dev/mmcblk0p2 to be 256 MiB
