Thanks, fixed!
The new commit message is the following:

| ci: introduce workflow for exotic builds
|
| This workflow is well-suited for test specific builds like dual-number
| mode on x86_x64, build with disabled JIT or FFI, etc.
|
| For now, just the dual-number mode is added, due to the need to test
| future commits. If there is a need to add a new build type, then the
| `FLAVOR` column of CI matrix should be extended. Also, only Linux x86_64
| is tested, because we want to decrease resource usage in CI.

-DLUAJIT_SMART_STRINGS=1 is set by default, so it's OK not to set it
mannually.

OTOH, -DLUAJIT_ENABLE_CHECKHOOK is not set by default.
I prefer not to set it for this particular workflow, because I plan to
use it for very specific builds (even impossible for Tarantool) for
example with -DLUAJIT_DISABLE_JIT=ON, -DLUAJIT_DISABLE_FFI=ON flags.
Also, this flag is not set for default LuaJIT testing, so I tried to
make those workflows look similar.
But if we want to add this flag for default build or testing we should
add it for this workflow too.
CC-ed Igor to hear his opinion.
