[PATCH v2 0/4] configure: bugfixes and cleanups for CFLAGS |

Meson is placing -pie after -shared rather than before, and this
causes linking to fail while building the ArchLinux package for
QEMU.
But why is -pie ending up in the flags? Because LDFLAGS is an
environment variable, and changes to environment variables propagate
when configure does
LDFLAGS="-pie $LDFLAGS"
This happens without having to export the env. var again.
The solution is to simply rename the CFLAGS and LDFLAGS variables
used for flags that Meson takes care of by itself. The CFLAGS
variable was previously used for submodules as well, so patches
1 and 2 fix that as well.
I'm keeping Richard's reviewed-by since the changes are pretty
obvious from v1.
v1->v2: include -fno-pie flags as well, since tests/tcg needs them
handle empty CFLAGS and LDFLAGS too
place flags in the built-in options section of the cross file
Paolo Bonzini (4):
configure: cleanup invocation of submodule Make
configure: cleanup CFLAGS and LDFLAGS for submodules
configure: do not clobber environment CFLAGS/CXXFLAGS/LDFLAGS
configure: consistently pass CFLAGS/CXXFLAGS/LDFLAGS to meson
