Debug flags passed as extra args are parsed incorrectly #237

Enabling debugging output using export CPPINTEROP_EXTRA_INTERPRETER_ARGS="-mllvm -debug-only=jitcall" causes the compiler instance creation to fail with:

>>> import cppyy
error: error reading 'new'
1 error generated.
python: llvm-project/clang/include/clang/Frontend/CompilerInstance.h:506: 
clang::Sema& clang::CompilerInstance::getSema() const: Assertion 
`TheSema && "Compiler instance has no Sema object!"' failed.

This is specific to when running cppyy, while running it directly works : 

CPPINTEROP_EXTRA_INTERPRETER_ARGS="-mllvm -debug-only=jitcall"
