libvpx: do not hardcode -mfloat-api=softfp for ARM builds

| Configuration failed. This could reflect a misconfiguration of your
| toolchains, improper options selected, or another problem. If you
| don't see any useful error messages above, the next step is to look
| at the configure error log file (config.err) to determine what
| configure was trying to do when it died.

+Upstream-Status: Inappopriate [upstream has it done in other way]

+Problem is solved upstream but we have quite old version so backporting patches
