When a GPU session is destroyed, remove vgpu of session from scheduling
and as possible active vgpu. Otherwise, page faults might occur in case
already destroyed vgpu object is referenced during interrupt handling.
fixes#4881
Apparently we need to save the floating point arguments when entering
the linker in case "-fno-tree-vectorize" is at work. Otherwise this
registers get corrupted during jump slot relocation.
Fixes#4879
Either enable strict-alignment or disable FPU code generation by gcc
regarding bootstrap code, which cannot handle alignment faults during
initialization properly.

Issue genodelabs/genode#4827
Eliminate the creation of 'Genode::String's before the linker has been
self relocated, because 'Genode::String's will call 'Genode::strlen' on
construction from C-Strings, which has now become a GOT relative call,
while the GOT contains only zeros before relocation -> page fault at
IP 0.

An early version of nitpicker used a pointer as 'owner' with the null
pointer representing nitpicker's built-in views, which are nowadays
represented by 'Main::_global_view_ower'. The null-pointer check is a
left-over from the earlier days.
Fixes#4847
Since repos/base/board/pc/devices is empty, the run script no longer
works on PC. Nobody noticed because the use case of this run script -
as development test loop for the ps2 and fb_sdl - are better served by
other scenarios nowadays, e.g., using declaring 'build: ps2' for a
custom Sculpt OS build.
Removed in the context of issue #4860.
