build fails on inline function. Relevant output when using ccache:

However, when not using ccache, after make clean && make:

and different output in config.log:

Note -finline-functions in the second build and -fno-inline-functions in the first build. However the compile fails either way with the same error message.

How-To-Repeat: make clean && make
