# Subject: [patch 059/167] ppc64: override command line AS/LD/CC variables when adding -m64 and co for biarch compilers
|
|
# To: torvalds@osdl.org
|
|
# Cc: akpm@osdl.org, sven.luther@wanadoo.fr, anton@samba.org,
|
|
# benh@kernel.crashing.org, paulus@samba.org
|
|
# From: akpm@osdl.org
|
|
#
|
|
# The following kind of calls currently fails :
|
|
#
|
|
# make ARCH=ppc64 CC="gcc-3.4"
|
|
#
|
|
# Since the code for detecting a biarch compiler and adding the needed 64bit
|
|
# magic argument fails if the AS/LD/CC commands are overriden in the command
|
|
# line.
|
|
#
|
|
# The attached patch fixes this by using the make override and += directive,
|
|
# but i am not 100% sure this will work without gmake, as i am no Makefile
|
|
# expert.
