     * gcc-interface/Make-lang.in (ALL_ADAFLAGS): Remove NO_PIE_CFLAGS.  Add
     PICFLAG.  Use PICFLAG when building ada/b_gnat1.o and ada/b_gnatb.o.

     Remove NO_PIE_FLAG.

had first broken --enable-default-pie (and AFAICS was not approved by an Ada
maintainer), so the aforementioned change restored the previous working state.

No problem, sorry for not pinging you about it.  I'll make sure to CC you when
I post a fix for this PR.

I hadn't spotted this, so attempted an Ada build with gcc-14-20230702 and got
this:

make[3]: *** No rule to make target `../libiberty/pic/libiberty.a', needed by
`cc1-checksum.cc'.  Stop.
make[3]: Leaving directory
`/Volumes/Miscellaneous3/x86_64/gcc-14-20230702/gcc/gcc'

gcc-14-20230702/gcc/ is automatically configured with --enable-host-pie, should
libliberty/ be also?
