Fix export dynamic linker option

[AngryPenguinPL]

As of LLVM/Clang 18 and LLD18 linker with the -export-dynamic option compilation ends with an error: cc: error: unknown argument: '-export-dynamic'

For GCC and the default compiler this is not a problem. The problem occurs in Clang/LLD 18.

Fix tested on Mandriva via OpenMandrivaAssociation/flatpak@39f1c03

I'm not even sure why/whether we need this option (shared libraries export dynamic symbols anyway), but there's certainly no harm in putting it in the format that tells the compiler "pass this opaque option through to the linker".
