lld 16 will break builds due to incorrect linker version scripts

[aaronmondal]

Since the --no-undefined-version flag has been flipped in lld (https://reviews.llvm.org/D135402), this repo will fail to link due to the following incorrect version script assignments:

ld.lld: error: version script assignment of 'OPENCL_1.0' to symbol 'clCreateFromD3D10Buffer' failed: symbol not defined

grepping these symbols indeed seems to expose them all as undefined, except for clCreateImageFromD3D10Resource which seems to have some other issue.

On a side note, I noticed that amdocl.map and amdocl.def are tracked in this repo despite having *.in generator files. It may be a good idea to remove the generated files to avoid redundancy.
