Fix export dynamic linker option

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
