runtime config for x86 linux adds incorrect gcc -nopie flag

[Steve Beattie]

SBCL fails to build when gcc is configure to generate Position Independent Binaries. The runtime configs for SBCL in sbcl/src/runtime/Config.x86-linux and sbcl/src/runtime/Config.x86-64-linux attempt to take this into account via the following code snippets:

  # Hardened GCC enables PIE by default
  ifneq ($(shell $(CC) -dumpspecs 2>/dev/null | grep -e nopie),)
  CFLAGS += -fno-pie
  LINKFLAGS += -nopie
  LDFLAGS += -nopie
  endif

However, upstream gcc has standardized on the -no-pie flag (note embedded hyphen):

   https://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/doc/invoke.texi;h=515d948ce710a2fba98c586ea2efa05d4cf60979;hb=HEAD#l10620

as of upstream commit:

  https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=e9abca4f4a48fa8b1fd9778f6a3cd748e099e3bb

This causes SBCL to FTBFS in Ubuntu 16.10 on amd64 where -pie is enabled by default in gcc.

Patch to fix the -no-pie arguments.

And here's the the debdiff that incorporates the prior patch into the sbcl 1.3.3-1ubuntu1 package that FTBFS in yakkety -proposed.

sbcl (2:1.3.3-1ubuntu2) yakkety; urgency=medium

  * debian/patches/fix-no-pie-linux.patch: detect and pass the correct
    -no-pie flags to GCC to disable -fPIE. (LP: #1576871)
