It seems to be at least two issues, besides already fixed MAC entry
point:

1. The /usr/libexec/cc1 binary is broken after buildworld (at least on
   i386). Looking at the readelf output, I noted that .SUNW_ctf section
   is marked as PROGBITS and has some low alignment, that resulted in
   the following stripped binary:

   Program Headers:
   Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
   LOAD           0x000000 0x08048000 0x08048000 0x51943a 0x51943a R E 0x20
   LOAD           0x519440 0x08562000 0x08562000 0x05fc4 0x9be8c RW  0x20
   NOTE           0x000094 0x08048094 0x08048094 0x00018 0x00018 R   0x4

   Such ELF cannot beload due to unaligned segments.
   Note that I did not turned on CTF generation for world.

2. UP kernel breakage. The following patch fixed it for me:
