RTEMS Tools | rtems-ld: An unused undefined symbol stops the link (#43)

[Sebastian Huber (@sebhub)]

Issue created by Sebastian Huber: https://gitlab.rtems.org/rtems/tools/rtems-tools/-/work_items/43



The assembler of i386 and microblaze adds `_GLOBAL_OFFSET_TABLE_` as an undefined symbol to an object which uses a thread-local storage operator.  No relocation record references the symbol.  rtems-ld treats it as unresolved and stops with "symbol not found: _GLOBAL_OFFSET_TABLE_".

A Newlib built with `--enable-newlib-reent-thread-local` carries such objects, so no application which links them can become a RAP file.  The test `dl06` of RTEMS does not build on i386 and microblaze.

Found while running the RTEMS test suite on eleven simulators.  This description was created with Claude Code assistance.
