27da374e48 libdl: Add support to import base image TLS symbols 
This change requires an rtems-tools update for symbol generation.

Working architectures:
 - aarch64
 - arm
 - powerpc
 - sparc

No newlib TLS support but checked:
 - i386
 - m69k

Updates #4920

1c6ac88f93 cpukit/libdl/rtl-sym.c: Fix increment of variable 
In rtems_rtl_symbol_global_add() the loop that gets to the end of the symbol
table used "unsigned long" to increment the index for the table. For most
architectures this resulted in 4, but with AArch64, it results in 8. This
resulted in the symbols being read in wrong. Changing this to void* along with
changing the RISC-V specific code for 8 byte pointers in rtems-tools to work
independent of the architecture.

Updates #4673
Closes #4682

a2e1e30d98 libdl: Add a local symbol table to the object module. 
Adding a local symbol lets the relocator find local symbols referenced
in relocation records. The local symbol table is erased once the object
module has been loaded.
