AFAIK, you can statically link all of them... but it was a long time ago.
The real culprit for static linking is in the gnu glibc: pthread_cancel _does_
dlopen libgcc_s for "stack unwinding code" (just kill the stack, why unwind
it??). This is how you can bootstrap a system build with a glibc which does not
require an existing libgcc_s which depends itself on the libc (it breaks the
circular dep). But gcc is doomed anyway as it goes c++.
To summerize, you have any program which uses pthread_cancel, you MUST use
libgcc_s, here dies the static libgcc distros.
It seems musl lib has a pthread_cancel which does work with "libgcc_s dlopen
free" static linking...
