Summary

0015617: When assembler is enabled TI Compiler might end up with wrong archiver

Description

If "ENABLE(ASM)" is used in a TI-Toolchain project and something named ar(.exe) is present in your path, this archiver (ar) will be used and not the TI toolchain's ar6x!

Here's why:
CMakeDetermineCCompiler.cmake (line 153, [1]) and CMakeDetermineCXXCompiler.cmake have some special code/regex to get the toolchain prefix and suffix. CMakeDetermineASMCompiler.cmake does not contain this code.

What happeens?
- The ASM Compiler is processed, pre- and suffix are empty.
- CMakeFindBinUtils.cmake is processed and CMAKE_AR is filled witht he wrong archiver
- Subsequent languages (c/cxx) will not overwrite the wrong CMAKE_AR setting.

Steps To Reproduce

I managed to reproduce this easily on multiple machines (all windows):
1. Get a regular archiver named "ar" in your path. On windows something named ar.exe should do the trick
2. setup a project that uses the TI Toolchain
3. use ENABLE(ASM) in yourproject
