Description:
trying to use Profile Guided Optimization with mingw results in a lot of linker errors to gcov library (and adding -lgcov, --coverage, -fprofile-arcs, -ftest-coverage doesn't solve the issue)

Additional info:
* package version(s)
6.3.1-1
* config and/or log files etc.

Steps to reproduce:
compile any program with "-fprofile-generate" and "-fprofile-dir" flags

e.g.
i686-w64-mingw32-g++ -fprofile-generate -fprofile-dir=. hello.cpp -o hello.exe
This task depends upon
