Marius Vikhammer 385439213a change(pthread): changed pthread to not pull in init functions if not used
The pthread_init function would always get included in the binary,
even when no pthread functions were used.

This happens due to us using -u linker flags to force the linker to
consider the pthread library, to ensure the weak pthread functions in
the toolchain are overridden.

By restructing the code to rely on lazy inits instead we can avoid using
a init function, and therefor save some space.
