 make build more flexible
 Ensure least-surprise behaviour when CFLAGS CPPFLAGS LDFLAGS LIBS
 are set by usual means: either via the environment, as ./configure
 arguments, or as make arguments.
 Implicit Make rules handle this, adapt florist.gpr to do so.
 .
 Add a similar ADAFLAGS variable.
 .
 Allow override of Library_Version (via GPRBUILD_FLAGS).
 .
 Allow to build both relocatable and static libraries in a row.
 Distinct lib and obj directories are required.
 A LIBRARY_TYPE_OPTION make variable is convenient because it avoids a new
 ./configure run.
 These ideas may easily be extended to BUILD_TYPE THREADS and RTS.
 .
 Allow GPRBUILD_FLAGS to override default gprbuild command line.
 PROJECT_FLAGS has a distinct purpose, and may be set separately.
