wangjianyu3 877ea4f8d8 arch/x86: Add -P to CPP to suppress linemarkers. ... The x86 CPP definition used `gcc -E -x c` without `-P`, unlike every other arch's Toolchain.defs (arm, risc-v, avr, mips, misoc, or1k, z16, z80 all pass `-E -P -x c`). Without `-P`, cpp emits GNU linemarker lines (e.g. `# 0 "file"`) into its preprocessed output. boards/Board.mk's PREPROCESS macro runs RCSRCS init.rc files through $(CPP) before feeding them to apps/system/nxinit's parser. The parser (apps/system/nxinit/parser.c) matches each line against known section keywords ("on", "service", ...) with strncmp(); a leading linemarker line does not match any keyword and the parser returns -EINVAL, so any board that preprocesses an nxinit init.rc under x86 fails to parse it at boot. Reproduced independently on the host toolchain: `gcc -E -x c` on a minimal init.rc emits `# 0 "file"` lines; `gcc -E -P -x c` on the same input produces clean `service`/`on` lines only.
