This happens while running:

make -C scripts libmakepkg/executable/checksum.sh

The error you are getting is that this is not valid:

mapfile -t integlist < <(get_integlist)'

After every file generation, the Makefile will execute:

@$(BASH_SHELL) -O extglob -n $@

That is, it is running the file using bash's "-n" option; set -n will
cause the file to be read, but no commands to be executed, in an effort
to make sure the file works. This is why you are getting messages about
the syntax of the file.

So the question then is, what is this resolving to?

checking for bash...
/gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/bin/bash


It needs to be bash >= 4.4.0, and we have a check which is supposed to
enforce this:
https://git.archlinux.org/pacman.git/tree/configure.ac?h=v5.2.1#n201

What version is your bash program, and why might it be refusing to
recognize this bash syntax?

Aside: that log is indeed huge. Why is this happening so often:

/gnu/store/whkq7f2d702hqnrdd2cqskqxdx267283-profile/include/stdlib.h:257:4:
warning: ISO C does not support the ‘_Float64x’ type [-Wpedantic]
