Commit Message

Dario Binacchi Oct. 3, 2024, 4:26 p.m. UTC 
Building arp-scan with --with-libcap for the ARC target raises the
following error:

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 adds the dependency on BR2_TOOLCHAIN_HAS_ATOMIC_TEST_AND_SET
to libcap.

Additionally, besides libcap, it was necessary to add the dependency on
BR2_TOOLCHAIN_HAS_ATOMIC_TEST_AND_SET to other packages to remove
warnings of this type:

WARNING: unmet direct dependencies detected for BR2_PACKAGE_LIBCAP
  Depends on [n]: BR2_USE_MMU [=y] && BR2_TOOLCHAIN_HAS_ATOMIC_TEST_AND_SET [=n]
  Selected by [y]:
  - BR2_PACKAGE_RNG_TOOLS [=y] && BR2_TOOLCHAIN_HAS_THREADS_NPTL [=y] && BR2_USE_MMU [=y]
