The build of libcap fails for ARC Targets which don't have the
ATOMICS_EXT flag set:

configure:5053: checking for cap_set_proc in -lcap

cap_proc.c:(.text+0x78): undefined reference to `__atomic_test_and_set'

configure:5086: result: no
configure:5097: error: libcap support was requested but the library was not found

The patch disables BR2_TOOLCHAIN_HAS_ATOMIC_TEST_AND_SET for BR2_arc
without BR2_ARC_ATOMIC_EXT.

Fixes:
