Golang buildmode PIE

Summary

Change default build mode of golang in Fedora packaging macros to buildmode=pie, which results in packages using them to produce Position Independent Executables. Another part of the change is to pass the Fedora hardened linker flags to the external linker(regular system linker). In result reducing exploit-ability of binaries.

Detailed Description

Change default build mode of golang in Fedora packaging macros to buildmode=pie, which results in packages using them to produce Position Independent Executables. Another part of the change is to pass the Fedora hardened linker flags to the external linker(regular system linker). This will only affect packages that depend on golang packaging macros for their build. This should be first step towards mandating this on all packages that provide binaries based on golang in whole distribution via Go packaging guidelines(which is out of scope for this change proposal).


Benefit to Fedora

Reducing exploit surface of golang based packages providing binaries.
