* Makefile.in (earmsymbian.c): Depend on armbpabi.sc, not elf.sc.
* ldexp.h (segment_type): New type. (segments): New variable. * ldexp.c (segments): New variable. (exp_print_token): Handle SEGMENT_START. (fold_binary): Likewise. * ldgram.y (SEGMENT_START): Declare it as a token. (exp): Handle SEGMENT_START. * ldlang.h (lang_address_statement_type): Add segment field. (lang_section_start): Change prototype. * ldlang.c (map_input_to_output_sections): Do not process section assignments if a corresponding SEGMENT_START has already been seen. (lang_section_start): Add segment parameter. * ldlex.l (SEGMENT_START): Add it. * lexsup.c (seg_segment_start): New function. (parse_args): Use it for -Tbss, -Tdata, and -Ttext. * ld.texinfo (SEGMENT_START): Document it. * emulparams/armsymbian.sh (EMBEDDED): Set it. * scripttempl/armbpabi.sc: Use SEGMENT_START to control segment base addresses.
