Description of problem:
With the update to RPM 4.17 alpha, our packages with Python interpreters (at least Python 3.5, 3.6, 3.7, 3.8, 3.9) no longer build.

See for example https://koschei.fedoraproject.org/package/python3.9?collection=f35

The error is:
+ %apply_patch -q /builddir/build/SOURCES/00189-use-rpm-wheels.patch
/var/tmp/rpm-tmp.Hz12p3: line 66: fg: no job control

It appears that a publicly available macro was just removed without any deprecation.

I've searched the release note and it only contains:
> Fix %apply_patch internal helper macro naming (#1357)

It doesn't say the macro was removed in a backwards incompatible manner. Please don't just remove working things like that :/

It was removed in https://github.com/rpm-software-management/rpm/pull/1512 presumably because it was reported as hard to use with %setup in https://github.com/rpm-software-management/rpm/issues/1357

%apply_patch works quite nicely with %autosetup -N. Please don't make us change several Python spec files that use it just for the sake of "this was never intended to be used" -- convenient macros are convenient, removing them makes packaging harder.


Version-Release number of selected component (if applicable): rpm-4.16.90-0.git15395.2.fc35


How reproducible: Easy


Steps to Reproduce:
1. Use %apply_patch in spec

Actual results:
Macro is expanded to literal "%apply_patch", shell says:
fg: no job control

Expected results:
Macro is expanded to an actual command to apply the patch (exact form depending on what value was used for %autosetup -S).
Patch is applied.
