Re: grep-3.8.11-908f on NetBSD 9.0

[Bruno Haible]

On NetBSD 9.0, the compilation succeeds and 1 test fails:

FAIL: filename-lineno

Since the test suite log contains the string
  grep: Shared object "libpcre2-8.so.0" not found
I looked around for libpcre. Indeed, there is a file
  /usr/pkg/lib/libpcre2-8.so.0
that is a symbolic link pointing to
  /usr/pkg/lib/libpcre2-8.so.0.10.2
and the latter is an ELF shared library.

The reason why it could not be found is probably that /usr/pkg/lib is not
among the runtime linker's search path and not declared as an RPATH:

$ readelf -d grep

I plan to fix the missing/broken rpath problem with pkgconfig this year [1];
this ought to fix this situation. Therefore I wouldn't mind if you leave
this problem aside for now.
