Only assign the environ in the startup code when environ is NULL. Preloaded library could have changed the environment, and unconditional assingment to the environ undoes the customization. The binaries needs to be recompiled to get the fix.
Move the common code to set up environ and __progname into the helper. Note that ia64 possibly not fixed, due to it still using old csu.

Stop calling _init/_fini methods from crt1 for dynamic binaries. Do call preinit, init and fini arrays methods from crt1 for static binaries.
Mark new crt1 with FreeBSD-specific ELF note.
Move some common crt1 code into new MI file ignore_init.c, to reduce duplication. Also, conservatively adjust nearby sources for style.

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 [1]. Hide and localize _start1 symbol used as an interface between asm and C code.

The main reason for this is to reduce diffs between all the crt1.c's.
Assembler macros are tidied up and made as similar as sanely possible. The macros are translated into C (__inline static) functions for lint.
Declaration orders are made the same. Declarations are all ISOfied and tidied up.
Comment contents have gratuitous diffs removed.
The net result is a bunch of crt1.c's that are 90% the same. It may be possible to now encapsulate the differences in one MD header, and have only one MI crt1.c file (although the macros to do this may be ugly).
