Dear Maintainer,
* Micropython FTBFS on multiple architectures
* Fixed by pulling in upstream change of variable type
*** /tmp/tmpvi9f9xor/bug_body
In Ubuntu, the attached patch was applied to achieve the following:
Successfully building mircopython on all architectures. These failures
are ocurring in Debian as well.
* Change subpkg_tried to a static variable to avoid clobbering by longjmp
(LP: #1931955)
Thanks for considering the patch.

+Description: Change a potentially clobbered variable to static
+ There was a bool that was not static and potentially clobbered. This was
causing build
+ failures in certain architectures and is fixed by making it a static bool.
