Log:
  stand/i386/libi386: rename .s file to .S to use Clang IAS
  
  As part of the migration away from obsolete binutils we want to retire
  GNU as.  Most assembly files used on amd64 have a .S extension and are
  assembled with Clang's Integrated Assembler (IAS); rename pxetram.s to
  .S to use IAS as well.
  
  The generated .text is identical (the entire .o file is not, as Clang
  adds debug info.)
