Makefile: Don't generate position independent code

Since gcc-8 the --enable-default-pie starts producing code which assembler
can't translate in case of U-Boot. The build fails with

  {standard input}: Assembler messages:
  {standard input}:21100: Error: junk at end of line, first unrecognized character is `@'
  {standard input}:21120: Error: junk at end of line, first unrecognized character is `@'

and so on.

This is usually the case for x86 platform because in many cases it uses host
compiler from the Linux distributions, where PIE is enabled by default.
Previously (gcc-7 and earlier) that was a potential issue due to absence of
constructions like

  .long   end.5561@gotoff-start.5558@gotoff

which are a cause of above error messages in gcc-8.

Fix all these by disabling PIE on Makefile level.
