Remove useless definitions of make macros

These symbols would only be used if STATIC_BUILD is true:
  INCLUDE_CUSTOM_EXTENSION_SYMBOLS
  INCLUDE_CUSTOM_EXTENSION_LIB
The configuration option --enable-static-build is only accepted on
macOS, but we don't use that option and it would fail anyway with
errors like
  No rule to make target .../vm/runtime/libmanagement_ext.a
and various other static libraries.

Also remove redundant '-c' from CFLAGS.
