Title: cpu/cc2538: add the exception handling frame section "eh_frame" to the linker script.

Fixes linker errors on newer toolchains, for example:
```
ld: foo.elf section `.eh_frame' will not fit in region `cca'
ld: region `cca' overflowed by 40 bytes
```
I started seeing these errors following an upgrade to Ubuntu Utopic.
