| Back to the patch - does the attached work for you?

The attached patch does not works for me as I wrote earlier, here are

| Subject: [PATCH] build: use distributed man pages when running with --help
|  fails

| When building against an incompatible GLIBC version compared to that
| on the build host, then running the just-built binary might fail
| although it is the same platform - thus CROSS_COMPILING is false.
| As a result, generating the man pages fails.

| * man/local.mk (.x.1): Add a check to verify that running the utility
| with --help succeeds, otherwise falling back to using 'dummy-man'.
