Fix build for binutils 2.45.1 with GAS support

- Fix BFD target struct for 2.45.1 API (remove TARGET_MERGE_SECTIONS)
- Fix ppc-dis.c variable names for 2.45.1 (dialect/sticky locals)
- Guard OBJ_XCOFF in tc-ppc.h to exclude TE_PE targets
- Fix md_apply_fix XCOFF-only code path for PE/COFF builds
- Remove broken LD aixppc emulation entry (XCOFF-only)
- Match gc-wii-binutils host build pattern (no patches needed)
- Use ftpmirror.gnu.org for reliable downloads
