Part of the NodeJS build builds V8, which at some stage tries to call
ar with all objects with *absolute* paths (and printf the command line
first).
This will fail if the build path is too long:
make[1]: execvp: printf: Argument list too long
when trying to create Release/obj.target/deps/v8/gypfiles/libv8_base.a
via below gyp-generated out/Makefile rule:
cmd_alink_thin = rm -f $@ && $(AR.$(TOOLSET)) crsT $@ $(filter %.o,$^)
i.e. something like
printf rm -f Release/obj.target/deps/v8/gypfiles/libv8_base.a && arm-poky-linux-musleabi-gcc-ar crsT Release/obj.target/deps/v8/gypfiles/libv8_base.a ...
The above failure happened on a build-directory S with 204 characters
on a Jenkins machine.
While one could probably increase the ulimit on that specific machine,
that would be a pretty specific build machine fix which would need to
be applied everywhere, or switch to non-verbose builds / compilation,
but fortunately we can change all object references to be relative to
the build directory itself by setting the builddir_name make variable
and thus avoid the other two possible work-arounds.
