bmake updated to 20240711

[Jonathan Perkin <jperkin%mnx.io@localhost>]

I've tested this as much as possible, but please let me know ASAP if you 
are running on some other platform and you see either a build issue or 
any failing tests.

This update contains over 4 years of changes, but notably allows us to 
start supporting longer command lines in pkgsrc infrastructure (see 
recent discussion around grafana checksum generation).

Cheers,
