I tried bootstrapping (from a separate account I set up on the
machine to make sure I don't mess up anybody else's stuff)
with the options

../gcc/configure \
         --prefix=$HOME \
         --enable-languages=c,c++,fortran \
         --disable-plugin \
         --enable-checking \
         --enable-stage1-checking \
         --enable-gnu-indirect-function \
         --enable-maintainer-mode \
         --disable-libgomp \
         --enable-decimal-float \
         --enable-secureplt \
         --enable-threads=posix \
         --enable-__cxa_atexit \
         --with-cpu=power9 \
         --with-long-double-128 \
         --with-as=/opt/at15.0/bin/as \
         --with-ld=/opt/at15.0/bin/ld \
         --with-gnu-as=/opt/at15.0/bin/as \
         --with-gnu-ld=/opt/at15.0/bin/ld \
         --with-advance-toolchain=at15.0 \
         --with-system-zlib \
         --with-native-system-header-dir=/opt/at15.0/include \
         --without-ppl \
         --without-cloog \
         --without-isl

but it failed with

../../gcc/gcc/lto-compress.c:34:10: fatal error: zlib.h: No such file or 
directory

Any idea how to fix this?
