The c-shared is intented to build C libraries hence it
does not export main and it's initialization does not
set the fs register with arch_prctl() leading to a crash.
Use -buildmode=shared -buildmode=pie to produce a library
which export main and is position independant while having
and init calling arch_prctl().
With this patch and the arch_prctl() stuff I revived from
Pekka's previous go work the code now crash after resolving
__vdso_gettimeofday to null later when the scheduler is initialized.
