Support Oracle Berkeley DB and lmdb
Both Oracle Berkeley DB and lmdb fail on WSL as of build 18204. This is due to an issue with mmap described at https://github.com/Microsoft/WSL/issues/658 and https://github.com/Microsoft/WSL/issues/902
Please fix the mmap issue so that lmdb and Oracle Berkeley DB, and projects relying on them, work in WSL.
The mmap issue has much broader implications than BerkeleyDB or lmdb. bup or building Android from source fails as well because of dysfunct mmap functionality.

BerkeleyDB and everything like it shares the same pedigree.

This might be distinct from the Oracle Berkeley DB issue. Claiming it here was premature. lmdb certainly fails, now tracking at https://github.com/Microsoft/WSL/issues/3451
