  • Performance Improvement

Changelog entry (up to few sentences, required except for Non-significant/Documentation categories):
Removed "pie" code generation that gcc from Debian packages occasionally brings by default.

Detailed description (optional):
After upgrading from gcc-8 to gcc-9 in our CI about half a year ago, occasionally our code starts to be generated with "position independent executable" option. This leads to less efficient addressing of global const tables. We saw slight performance degradation in our CI but decided to not pay attention.
