On sparc there are 8-byte atomic loads and stores available in ISA
but not atomic increments. As a result linking fails as:
```
ld: src/libccache_lib.a(InodeCache.cpp.o):
undefined reference to symbol '__atomic_fetch_add_8@@LIBATOMIC_1.0'
ld: sparc-unknown-linux-gnu/8.2.0/libatomic.so.1:
error adding symbols: DSO missing from command line
```
The fix is to add increment into libatomic test.
tested on `sparc-unknown-linux-gnu` target.
