Thanks for providing this patch. Could you give a bit more details
about which libraries get installed, what is their name, etc. ?

Indeed, rather than ignoring files from /usr/lib/node_modules, it would
be a lot better to remove the libraries that are anyway not useful
because they don't match the CPU architecture of the target. This would
both reduce the filesystem size *and* solve the check-bin-arch issue.

If really this isn't possible, then we could define
NODEJS_BIN_ARCH_EXCLUDE in nodejs.mk, to exclude /usr/lib/node_modules/
from the check-bin-arch verification. It's not as good as preventing
the problem, but it's better than a global exclusion.

In order to investigate this, I tried to do a build with the stf NPM
package, but it failed on bufferutil. I tried the following Buildroot
defconfig:

BR2_arm=y
BR2_cortex_a8=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_LINARO_ARM=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_NODEJS=y
BR2_PACKAGE_NODEJS_MODULES_ADDITIONAL="stf"
# BR2_TARGET_ROOTFS_TAR is not set

And it resulted in this:

[...]
.../home/thomas/projets/buildroot/output/host/bin/npm install -g stf
[...]
> node-gyp rebuild || node suppress-error.js

  TOUCH Release/obj.target/DTraceProviderStub.stamp

> node-gyp rebuild

  CXX(target) Release/obj.target/bufferutil/src/bufferutil.o
In file included from ../../nan/nan.h:190:0,
                 from ../src/bufferutil.cc:16:

   return obj->ForceSet(GetCurrentContext(), key, value, attribs);
               ^~~~~~~~

Do you know what is going on ?

Thanks!
