Bernd Kuhls 3ac0f22f90 package/cpp-httplib: link with libatomic if needed ...

Buildroot commit 8dad17ea06 bumped the
package from 0.27.0 to 0.37.2. This bump includes upstream commit
464867a9ce
which added WebSocket support to version 0.33.0 and causes a build error
detected by the Gitlab pipelines for bootlin-sparc-uclibc:

/builds/bkuhls/buildroot/br-test-pkg/bootlin-sparc-uclibc/host/opt/ext-toolchain/bin/../lib/gcc/sparc-buildroot-linux-uclibc/14.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld:
 /tmp/cciyXsAR.ltrans6.ltrans.o: in function
 `httplib::ws::WebSocket::close(httplib::ws::CloseStatus,
 std::__cxx11::basic_string<char, std::char_traits<char>,
 std::allocator<char> > const&)':
<artificial>:(.text+0x6408): undefined reference to `__atomic_exchange_1'

To fix the problem we add -latomic to LDFLAGS when needed.
