CMake ignores the sysroot when testing the support of PIE, so the link test fails when it tries to check for PIE support and decides that it's not supported. Therefore we tell CMake that PIE is supported when using the osquery-toolchain and leave the automatic test for other toolchains. Temporarily disable PIE on executables built with the osquery-toolchain libFuzzer, since it has not been compiled with PIE/PIC support.
