From: Ralf Baechle Date: Wed, 22 Feb 2006 23:06:55 +0000 (+0000) Subject: [MIPS] Remove CONFIG_BUILD_ELF64. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8145095cd8fd466980ea6401f26a52e462275222;p=openwrt%2Fstaging%2Fblogic.git [MIPS] Remove CONFIG_BUILD_ELF64. This option is no longer usable with supported compilers. It will be replaced by usage of -msym32 in a separate patch.
