Linker uses wrong files with multiple executions #26

Closed pschichtel closed 5 years ago

pschichtel commented 6 years ago

I'm currently trying to cross-compile a library to all required target platforms (currently testing with x86_64 and aarch64, but I'm having trouble linking the binary on the second execution (aarch64) because the aarch64 gcc linker tries to link x86_64 objects.
