This is handled in the next patch, so forget it. Although I get a build failure on this
patch:
/home/smarchi/src/binutils-gdb/gdb/solib-dsbt.c: In function ‘int scan_dyntag(int, bfd*, CORE_ADDR*)’:
/home/smarchi/src/binutils-gdb/gdb/solib-dsbt.c:427:63: error: base operand of ‘->’ has non-pointer type ‘target_section_table’
427 | for (target_section = current_program_space->target_sections->sections;
