../ldrsrc_bin.c is generated from this directory's ldrsrc.c (real, unmodified upstream source - ps2sdk/ee/elf-loader2/src/ldrsrc/src/ldrsrc.c) via a standalone build outside ps2build's own pipeline, matching real upstream's own nested Makefile: compile ldrsrc.c against elf-loader.h/ elf_loader_common.h, link it alone (-nostdlib -nostartfiles -T linkfile, against only libkernel.a + libc_nano.a), objcopy -Obinary the result, then bin2c the raw binary into ldrsrc / size_ldrsrc.

Regenerate only if ldrsrc.c itself changes (rare - it's a small, stable relocator stub):
