Properly support -fPIE by linking PIE binaries with specially-built Scrt1.o instead of crt1.o, since the later is built as non-PIC. Separate i386-elf crt1.c into the pure assembler part and C code, supplying all data extracted by assembler stub as explicit parameters. Hide and localize _start1 symbol used as an interface between asm and C code.
