General Improvements for Sculpt

[Edoardo Mantovani]

HI Norman,

Extremely strange.. when I try to execute the core (|| time) elfs, the
following error appears:
cannot execute binary file: Exec format error

Note that I already encountered the following error when I tried to use any
elfs under /bin in the pre-compiled toolchain,
For fixing that I manually installed the toolchain (and, if I execute for
example the x86 gdb program under /bin, everything works well [no ELF
error]).
Regards,
Edoardo Mantovani, 2021
