These changes cause some regressions:
- distutils builds third-party extensions with LDFLAGS, which were used to build CPython. (This is more important regression.)
  This problem concerns Python 2.7 and 3.2.
- distutils builds third-party extensions with LDFLAGS environment variable passed twice to compiler (distutils uses LDSHARED, which now contains $(LDFLAGS), and uses LDFLAGS).
  This problem concerns Python 3.2.

Example for 3.2:
x86_64-pc-linux-gnu-gcc -pthread -shared ${LDFLAGS_from_CPython} ${LDFLAGS_from_current_environment} ${LDFLAGS_from_current_environment}  ${CFLAGS} ${object_files} -L/usr/lib64 -lpython3.2mu -o ${extension_module}
