Added dependency of IDL generated files on IDL compiler

It is expected that the IDL compiler executable is the first word in the
IDL_COMPILER variable. If the first word is not a file (e.g. shell
variable assignment), it will work correctly as $(wildcard ) is used and
it will return empty string in that case.
