Replace "cat file | grep pattern" with "grep pattern file", and quote a
few variables. Together that fixes all shellcheck errors.

Prefer stderr instead of stdout for error messages.
This is a good practice and can help CI error detecting and
reporting (0day in this case).

Remove the '-m4' option to grep to allow grep to process all of nm's
output. This avoids the nm warning:
nm terminated with signal 13 [Broken pipe]

Use a tool to check that the location of "fixed sections" are where
we expected them to be, which catches cases the linker script can't
(stubs being added to start of .text section), and which ends up
being neater.
Sample output:
ERROR: start_text address is c000000000008100, should be c000000000008000
ERROR: see comments in arch/powerpc/tools/head_check.sh
