Would be nice to see the Makefile in this tarball as well.

I assume this is actually building the modules, so it should be part of
the do_compile. Which you should be able to do by simply setting
MAKE_TARGET to "modules" in the recipe namespace (i.e. simply
MAKE_TARGET = "modules" in your recipe, outside of tasks).
I would strongly suggest to look at what was done for the do_compile and
do_install tasks inside the module class, you likely need something
awfully similar for your do_configure step.

Specifically look at the unset line and all the variables passed to the
or_runmake instruction.

EXTRA_CFLAGS="${CFLAGS}" modules

do_compile_append() {
export KERNEL_CFLAGS="-falign-functions=16"
Pretty sure this is not used since you'd set the variable after the
compile instruction has run (:append).
}
do_install() {
# Create directory for the modules
install -d ${D}/lib/modules/${KERNEL_VERSION}/kernel/backports/cypress
# Locate and install the kernel modules
find ${S} -name "brcmutil.ko" -exec install -m 0644 {}

Here is the recipe that I was compiling and I'm facing the issues.
Which version of Yocto are you using? Because the _ override syntax is
long EoL, we now use : instead, so it should be do_install:append(),
FILES:${PN}, do_compile:append() etc.... I see there are some
:remove/:append there, so it seems like you're either using dunfell
because both syntax are supported or something here just won't work as
it's one syntax or the other that works but not both.
Cheers,
Quentin
