This is from arch/arm/Makefile of linux-2.6.25.10:
ifeq ($(CONFIG_AEABI),y)
CFLAGS_ABI :=-mabi=aapcs-linux -mno-thumb-interwork
else
CFLAGS_ABI :=$(call cc-option,-mapcs-32,-mabi=apcs-gnu) $(call
cc-option,-mno-thumb-interwork,)
endif
so -mabi=aapcs-linux should only be enabled if the toolchain is using EABI.
alsa-lib.mk:
ifeq ($(BR2_arm),y)
ALSA_LIB_ABI:=-mabi=aapcs-linux
else
ALSA_LIB_ABI:=
endif
should probably be replaced with:
ifeq ($(BR2_ARM_EABI),y)
ALSA_LIB_ABI:=-mabi=aapcs-linux
else
ALSA_LIB_ABI:=
endif
