… PATH
Currently, in order to build the compat VDSO with Clang, this format
has to be used:
PATH=${BIN_FOLDER}:${PATH} make CC=clang
Prior to the addition of this file, this format would also be
acceptable:
make CC=${BIN_FOLDER}/clang
This is because the vdso32 Makefile uses cc-name instead of CC. After
this path, CC will still evaluate to clang for the first case as
expected but now the second case will use the specified Clang, rather
than the host's copy, which may not be compatible as shown below.
/usr/bin/as: unrecognized option '-mfloat-abi=soft'
clang-6.0: error: assembler command failed with exit code 1

Using (cc-name) directly leads to selection of first (cc-name) in path without respecting (CC) - in practice, this means a fallback to host clang under /usr/bin/clang.
32-bit cross compilers will still be respected.
