[meta-ti] [rocko/master][PATCH v2] ti-cgt-arm: "clean" library in do_configure

[Jacob Stiffler]

* Prevent a potential error as mklib will return an error if the
  library already exists.
* The error encountered is the following:

| >> ERROR: mklib: destination library .../work/x86_64-linux/ti-cgt-arm-native/16.9.2-r1/ti-cgt-arm-16.9.2/ti-cgt-arm_16.9.2.LTS/lib/rtsv7R4_A_le_v3D16_eabi.lib already exists
| WARNING: .../work/x86_64-linux/ti-cgt-arm-native/16.9.2-r1/temp/run.do_compile.13758:1 exit 1 from 'lib/mklib --pattern=rtsv7R4_A_le_v3D16_eabi.lib'
