[ipxe-devel] [PATCH v2] arch: i386: Check for -no-pie gcc option as well.

[Markos Chandras]

openSUSE Tumbleweed switched on PIE by default since gcc-7.1.1. However,
-nopie option is not a recognized upstream option so the existing check
fails with

gcc: error: unrecognized command line option '-nopie'; did you mean
'-no-pie'?

as such, we also need to check for '-no-pie' option as well.
