xtensa: remove ldso workaround by real pointer check
An abort() is only generated when gcc does not implement
a trap handler for the target architecture.
This fixes the abort() generation. Latest gcc git master
also contains a trap handler for xtensa.

mips: remove ISA choice
We don't add cpu specific CFLAGS to the build, so the
ISA config symbols for MIPS are noops.
Simple remove them.

- This selects the instruction set architecture of your MIPS CPU. This
- information is used for optimizing purposes. To build a library that
- will run on any MIPS CPU, you can specify "Generic (MIPS I)" here.
- If you pick anything other than "Generic (MIPS I)," there is no
- guarantee that uClibc will even run on anything other than the
- selected processor type.
-
- You should probably select the MIPS ISA that best matches the
- CPU you will be using on your device. uClibc will be tuned
- for that architecture.
