The original arch-arm libGLESv1_CM.so and libGLESv2.so symbols in
android-4 and android-5 were correct. They didn't include some vendor
extension symbols that are in the platform library but that apps
should query at runtime rather than link against.
When arch-x86 and arch-mips were added in android-9, they mistakenly
included these extension symbols. Oh well, for compatibility we can't
fix that now.
The android-20 symbols for all architectures were copied from x86 or
mips, and include the extension symbols. To avoid spreading the
mistake, this change:
(a) Removes the symbol files for architectures that existed in earlier
versions of the platform, since they shouldn't change in android-20.
(b) Removes the extension symbols on 64-bit platforms, so they match
the symbols in arch-arm.
