There is indeed a bug in commit
e9a5f5843d0685c69b3c379b91bb9cce8864b8a2 in that it no longer
builds/installs the flex binary, for both the host and target variant.

We do want to build the flex binary when building host-flex (since it's
needed as a build dependency for other packages), but we do *NOT* want
to build the flex binary when building the target flex, because
building the flex binary is not possible on noMMU platforms.

Bottom line: e9a5f5843d0685c69b3c379b91bb9cce8864b8a2 is bogus, but
your patch is also bogus.

Best regards,

Thomas
