doc/Makefile: Limit memory consumption when generating docs

Browse Source 
* doc/Makefile: Do not disable garbage collection completely (as it
was after 3684c7967) when generating docs.  Use no too large 50Mb
`gc-cons-threshold' instead.

See
https://yhetil.org/emacs-devel/9778F176-E724-4E61-B0FB-327BCDD316C0@acm.org
for the testing behind the 50Mb constant.

# We increase GC threshold when generating documentation. This
# imrpoves the performance significantly. See

# Too high number may cause memory overflow (for example, it has
# happened in CI during automated build). We choose 50Mb threshold,
# based on the above discussion.
