Hi,
I'd like to see an option to disable the automated deletion of the tmp-<pkgname> directory, and possibly also enable its reuse, when it exists. This has some advantages e.g. for preparing new .mk files:
(1) Unpacking the archive is only needed once.
(2) Different options for e.g. configure can be tried within the tmp-<pkgname> directory quicker because of (1).
(3) In general, it makes debugging / tuning a package easier since all the files are kept even if the build completes successfully.
This could be triggered with an environment variable, e.g.
MINGW_CROSS_ENV_KEEP_TMP=1
