Does not compile on raspi B+ with Exec format error

[g-vidal]

Hi, I cannot compile on a raspberry Pi B+ with the following error message I suspect a wrong PLATFORM_ option but I cannot find a solution :

/bin/sh: 1: scripts/basic/fixdep: Exec format error
make[2]: *** [scripts/Makefile.build:266: /var/lib/dkms/rtl88x2bu/5.6.1/build/core/rtw_io.o] Error 2

My config is Linux ********* 5.4.83-v7 #1 SMP Sun Jan 24 23:03:23 CET 2021 armv7l GNU/Linux , I checked many CONFIG_PLATFORM_ARM_ without any success ; here is the compiler used :

gcc -v

Can you try the latest branch (5.8.7.1_35809.20191129_COEX20191120-7777) and share the full output of attempting to compile if it fails? I have it working (with lots of warnings, but no errors) on a Pi1B and a P4 -- would be good to see if there's something unexpected w/ the B+.
