If the `nop` binary used in `parallel/test-process-execve-no-args` has been linked to external libraries, it may need an environment variable such as `LD_LIBRARY_PATH` to be set to be able to run. Assume if `node` has been configured to link against any external libraries then `nop` has also been, and in that case pass through the environment variables to the test.

hmm actually this may be a bug in Node.js. |

This is a really subtle problem with
parallel/test-process-execve-no-argsthat has not been caught until now because we've been running thesharedlibs_*CI on Ubuntu with gcc and suddenly came up when we tested switching over to clang.With many of the
sharedlibs_*builds we add libraries onto the command line, e.g. for OpenSSLThe
nopbinary used by the test doesn't need any of that, so gcc on Ubuntu (and other Debian-derived Linux distributions) will not link thenopbinary to those additional libraries1. Howevergccon other Linux distributions, and clang do not do this by default so thenopbinary will be linked to the additional libraries.parallel/test-process-execve-no-argscurrently doesn't pass on the environment variables, so ifLD_LIBRARY_PATH(or equivalent for the platform) needed to be set to find those additional libraries the test would not be able to successfully runnop.For completeness, it's possible to replicate the Ubuntu gcc default behaviour by passing
--as-neededthrough to the linker (e.g.-Wl,--as-needed) but that's sensitive to the linker being used (e.g. the default linker on AIX/Illumos does not support that flag). In an ideal world we would not be appending the additional libraries onto the command line when linkingnop, but that would be tricky to do with the wayconfigureandgypcurrently work.FYI @nodejs/distros
