No. These flags are defined in numpy.distutils config_fc command
(that f2py internally uses for compiling fortran codes)
while for compiling C code f2py completely
relies on distutils features.

Yes, afaik this is what distutils recommends.
Another option is to build C library with your favorite compiler options (
plus options like -fPIC to support shared libraries)
and just use `-lmyfavoriteclib` in f2py command line when building
Python extension module.

No. Though it is in my todo list. So, the current solution is still to
to use .c files and a .pyf file in parallel.
