tcf-agent: enable default target debugging features
A number of features were disabled in OE due to historic problems
on ARM. In tcf-agent 1.4, they compile cleanly on all architectures
besides mips and libc-musl. These features are required for target
debugging with Eclipse Neon, CDT and TCF plugins - for example used
by Xilinx Vivado SDK 2016.4.
For MIPS and libc-musl, at least re-enable SERVICE_Symbols and
SERVICE_LineNumbers which compile cleanly.
