Commit 858805b336be1cabb3d9033adaa3676574d12e37 ("kbuild: add $(BASH) to 
run scripts with bash-extension") breaks my kernel test flow that targets 
the HiFive Unleashed board.  The boot traps during BBL early boot and 
stops.  QEMU is unaffected.  Reverting 858805b336be fixes the issue.

I haven't yet had the opportunity to root-cause the issue.  The issue may 
be related to idiosyncracies in my local boot testing process, rather 
than this commit.

The reason is because
a shell script using bash-extension is run by 'sh' instead of 'bash'.

Run 'git grep CONFIG_SHELL', then can you find a suspicious script?
Is there a warning/error message in the build log?
