gcc-8_8.3.0.3-3+rebuild 没有默认使能pie

[RevySR]

SUMMARY | 问题概要

gcc 默认应该使能pie 但是因为发行版识别修改成uos/deepin导致默认pie消失了
所以各个项目才不得不强加-pie参数

# pie by default --------------------
with_pie :=
ifeq ($(distribution),Debian)
  ifeq (,$(filter $(distrelease),wheezy squeeze jessie))
    pie_archs = amd64 arm64 armel armhf i386 \
		mips mipsel mips64 mips64el mipsn32 mipsn32el \
		mipsr6 mipsr6el mips64r6 mips64r6el mipsn32r6 mipsn32r6el \
		ppc64el s390x sparc sparc64 kfreebsd-amd64 kfreebsd-i386 \
		hurd-i386 riscv64
  endif
  ifeq (,$(filter $(distrelease),wheezy squeeze jessie stretch))
    pie_archs += powerpc ppc64
  endif
else ifeq ($(distribution),Ubuntu)
  ifeq (,$(filter $(distrelease),lucid precise trusty utopic vivid wily))
    pie_archs = s390x
  endif
  ifeq (,$(filter $(distrelease),lucid precise trusty utopic vivid wily xenial))
    pie_archs += amd64 ppc64el
  endif
  ifeq (,$(filter $(distrelease),lucid precise trusty utopic vivid wily xenial yakkety zesty))
    pie_archs += armhf arm64 i386
  endif
  pie_archs += riscv64
endif
ifneq (,$(filter $(DEB_TARGET_ARCH),$(pie_archs)))
  with_pie := yes
endif
ifeq ($(trunk_build),yes)
  with_pie := disabled for trunk builds
endif

STEPS TO REPRODUCE | 复现步骤

dget -d https://community-packages.deepin.com/deepin/pool/main/g/gcc-8/gcc-8_8.3.0.3-3%2Brebuild.dsc
dpkg-source -x gcc-8_8.3.0.3-3%2Brebuild.dsc
cd gcc-8-8.3.0.3/debian

vim +1237 rules.defs

就可以发现没有识别uos/deepin相关的 导致default-pie丢失 与其他发行版行为不一致

@Rabenda v23的gcc也有同样的问题吧？

重新编译的gcc有 现在还没重新编译

@UTsweetyfish 看下这个问题，v23的gcc版本上加一下关于uos/deepin的判断

v23 已 merge
