The --sysroot option makes it less likely that artifacts from the host pollute the build, for example headers from /usr/include. The most important difference for the Fedora sysroot will be that the absolute path in the libc.so linker script will be interpreted as local to the --sysroot tree (kind of like chroot). If you just use -L…, it would go to /usr/lib64 outside of the sysroot instead. A configure invocation in the above style would not produce working binaries for many GNU/Linux packages because it results in host paths (not target paths) baked into the binary. For example, a cross-built info viewer is still expected to look into /usr/share/info, and not the sysroot-prefixed path. However, --sysroot needs to be enabled in the toolchain, and I don't know if we do that for the mingw toolchain.
