Description
Feature or enhancement
Proposal:
https://github.com/python/cpython/pull/148238 removes -fno-plt for Linux AArch64. The JIT code generated has improved.
We should do a similar thing for Linux x86-64. I tried on that PR but the change requires more investigation.
Has this already been discussed elsewhere?
I have already discussed this feature proposal on Discourse

Research direction
Begin by reading PR #148238, which removes the flag for Linux AArch64, and review the linked Discourse discussion. Compare that approach with Linux x86-64 JIT behavior; done means determining whether -fno-plt can be dropped without regressions and validating the generated code improvement.
