Pass -no-pie to GCC only if GCC defaults to PIE [BZ #22614]
After --enable-static-pie is added to configure, libc_cv_pie_default is set to yes when either --enable-static-pie is used to configure glibc or GCC defaults to PIE. We should set no-pie-ldflag to -no-pie, which is supported on GCC 6 and later, only if GCC defaults to PIE, not when --enable-static-pie is used to configure glibc. Tested on x32 with --enable-static-pie using GCC 5 and without --enable-static-pie using GCC 7. [BZ #22614] * Makeconfig (no-pie-ldflag): Set to -no-pie only if $(cc-pie-default) == yes. * config.make.in (cc-pie-default): New. * configure.ac (libc_cv_pie_default): Renamed to ... (libc_cv_cc_pie_default): This. (libc_cv_pie_default): Set to $libc_cv_cc_pie_default. * configure: Regenerated.
