Pass -no-pie to GCC only if GCC defaults to PIE [BZ #22614]
$(no-pie-ldflag) is no longer effective since no-pie-ldflag is defined
to -no-pie only if GCC defaults to PIE. When --enable-static-pie is
used to configure glibc build and GCC doesn't default to PIE. no-pie-ldflag
is undefined and these tests:
elf/Makefile:LDFLAGS-tst-dlopen-aout = $(no-pie-ldflag)
elf/Makefile:LDFLAGS-tst-prelink = $(no-pie-ldflag)
elf/Makefile:LDFLAGS-tst-main1 = $(no-pie-ldflag)
gmon/Makefile:LDFLAGS-tst-gmon := $(no-pie-ldflag)
may fail to link. This patch replaces "-pie" with
$(if $($(@F)-no-pie),$(no-pie-ldflag),-pie)
and repleces
LDFLAGS-* = $(no-pie-ldflag)
with
tst-*-no-pie = yes
so that tst-dlopen-aout, tst-prelink, tst-main1 and tst-gmon are always
built as non-PIE, with and without --enable-static-pie, regardless if
GCC defaults to PIE or non-PIE.
Tested with build-many-glibcs.py without --enable-static-pie as well as
with --enable-static-pie for x86_64, x32 and i686.
