Build failed on FreeBSD w/ clang 10

[gaod]

At the latest release 8.1.1, while enabling WCCP on FreeBSD 12.2 with built-in clang 10.0.1:

ld: error: undefined symbol: wccp::detail::cache::CacheData::idAddr() const
>>> referenced by WccpMsg.cc:1029
>>>               WccpMsg.o:(wccp::CacheViewComp::fill(wccp::MsgBuffer&, wccp::detail::cache::GroupData const&)) in archive wccp/libwccp.a

c++: error: linker command failed with exit code 1 (use -v to see invocation)

But it can pass on FreeBSD 12.2 with gcc 9.3.

Confirmed that the link error happens on master as well. Not really a workaround but it links successfully if I run configure with --enable-debug.

Removing inline solves the issue, but I'm not sure if we want to do it.

Lines 360 to 364 in a1a47b9

	inline uint32_t
	detail::cache::CacheData::idAddr() const
	{
	return m_id.getAddr();
	}

@SolidWallOfCode Can you take a look?
