It's not straightforward to fix. We need to detect a correct
cross-prefix for strip. There is something in roms/Makefile:
#
# cross compiler auto detection
#
path := $(subst :, ,$(PATH))
system := $(shell uname -s | tr "A-Z" "a-z")
# first find cross binutils in path
find-cross-ld = $(firstword $(wildcard $(patsubst
%,%/$(1)-*$(system)*-ld,$(path))))
# then check we have cross gcc too
find-cross-gcc = $(firstword $(wildcard $(patsubst %ld,%gcc,$(call
find-cross-ld,$(1)))))
# finally strip off path + toolname so we get the prefix
find-cross-prefix = $(subst gcc,,$(notdir $(call find-cross-gcc,$(1))))
powerpc64_cross_prefix := $(call find-cross-prefix,powerpc64)
powerpc_cross_prefix := $(call find-cross-prefix,powerpc)
x86_64_cross_prefix := $(call find-cross-prefix,x86_64)
and then:
$(powerpc_cross_prefix)strip <...>
However, to solve this problem, it would be enough to export
${cross_prefix} from configure to config-host.mak and do like this:
$(CROSS_PREFIX)strip <...>
Kind regards,
