[oe] [meta-oe][PATCH] librelp: Pass Wno-error to compiler

[Khem Raj]

After autoconf-archive was upgraded to 2019.01.06 it started to add
extra warning flags via WARN_CFLAGS along with -Werror which means that
now compiler could be stricter and break the build if any of the new
warnings are flagged

The difference is

old

WARN_CFLAGS='-fno-strict-aliasing  -Wimplicit-function-declaration -Wold-style-definition -Wjump-misses-init -Werror -Wno-suggest-attribute=format -Wunused-parameter -Wmissing-field-initializers'

new

WARN_CFLAGS='-fno-strict-aliasing  -Wimplicit-function-declaration -Wold-style-definition -Wjump-misses-init -Wall -Wextra -Wundef -Wwrite-strings -Wpointer-arith -Wmissing-declarations -Wredundant-decls -Wno-unused-parameter -Wno-missing-field-initializers -Wformat=2 -Wcast-align -Wformat-nonliteral -Wformat-security -Wsign-compare -Wstrict-aliasing -Wshadow -Winline -Wpacked -Wmissing-format-attribute -Wmissing-noreturn -Winit-self -Wmissing-include-dirs -Wunused-but-set-variable -Warray-bounds -Wreturn-type -Wswitch-enum -Wswitch-default -Wduplicated-cond -Wduplicated-branches -Wlogical-op -Wrestrict -Wnull-dereference -Wdouble-promotion -pedantic -Wunused-parameter -Wmissing-field-initializers -Werror -Wno-suggest-attribute=format -Wunused-parameter -Wmissing-field-initializers'

Hence we started seing build failure like https://errors.yoctoproject.org/Errors/Details/252684/

This fix just turns off warnings-as-errors so build can still go on, if
we need to fix the warnings they still are present in log.do_compile
