[Buildroot] invalid commads passed in compiler line results in failure.

[daggs]

Greetings,

I'm trying to add a new pkg what compile a kernel driver for arm, upon compilation, I get these errors:
aarch64-linux-gcc.br_real: error: unrecognized argument in option ?-mabi=apcs-gnu?
aarch64-linux-gcc.br_real: note: valid arguments to ?-mabi=? are: ilp32 lp64
aarch64-linux-gcc.br_real: error: unrecognized command line option ?-mapcs?; did you mean ?--specs??
aarch64-linux-gcc.br_real: error: unrecognized command line option ?-mno-sched-prolog?; did you mean ?-Wno-sign-promo??
aarch64-linux-gcc.br_real: error: unrecognized command line option ?-msoft-float?

asking google suggests that I'm not setting the CROSS_COMPILE var properly but from what I see, there are no problems.
the line I'm using in the mk file is this:
$(MAKE) CROSS_COMPILE="$(TARGET_CROSS)" -C $(@D)/driver/src/devicedrv/mali/ $(TARGET_CONFIGURE_OPTS) 

the entire compilation line is this:

any ideas what can be the issue?

Thanks,

You are passing ARM options to an AArch64 compiler: this cannot work.

I thought there is something funny in the makefile when it comes to cross compile of arm64, that is why I've searched the code for either apcs, no-sched-prolog or soft-float but I didn't found such.
I wonder of there is a -m32 like switch. I'll follow the arm switches.

Thanks,
