[oe] [meta-oe][PATCH v2] log4cplus: remove gold linker setting

[mingli.yu at windriver.com]

From: Mingli Yu <mingli.yu at windriver.com>

After commit[3a7abb175 log4cplus: Fix build with gold linker]
applied, with below logic in conf/local.conf
MACHINE ??= "qemumips64"
MULTILIB_GLOBAL_VARIANTS_append = " libn32"
MULTILIBS ?= "multilib:lib32 multilib:libn32"
DEFAULTTUNE_virtclass-multilib-lib32 ?= "mips"
DEFAULTTUNE_virtclass-multilib-libn32 ?= "mips64-n32"
require conf/multilib.conf

There comes below configure error:
 $ bitbake libn32-log4cplus
 | checking for the pthreads library -lpthread... no
 | configure: error: Requested threads support but no threads were found.

Actually the logic[CXXFLAGS += "-fuse-ld=gold"] is not
needed in commit[3a7abb175 log4cplus: Fix build with gold linker],
so remove it to fix the above configure error.
