When building libsoup within the SDK, the following usually nonfatal warning
is causing the build to fail:
make[6]: Entering directory '.../build_dir/target-arm_xscale_musl-1.1.14_eabi/libsoup-2.53.2/libsoup'
CC libsoup_2_4_la-soup-address.lo
cc1: error: .../staging_dir/target-arm_xscale_musl-1.1.14_eabi/include: No such file or directory [-Werror=missing-include-dirs]
cc1: some warnings being treated as errors
Makefile:962: recipe for target 'libsoup_2_4_la-soup-address.lo' failed
Use the upstream `--disable-more-warnings` configure switch to disable this
class of `-Werror` flags.
Also drop the shipped copy of `intltool.m4` to force using the system wide one
which does not require the `XML::Parser` module to be installed (see #2771).
