[PATCH master] Revert "MAKEALL: query CONFIG_64BIT before make instead of CONFIG_ARM64 after"

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

The commit being reverted here assumed that all defconfigs have a
corresponding file, but this doesn't hold true for generated configs
like multi_v8_efi_defconfig.

The issue that was meant to be addressed disappeared after rerunning
the test, so it might have been just a fluke (or triggered by shuffle,
although I was unable to reproduce with the same seed).

Until better understood, reinstate the old code.
