Cross compiler build for Ada build fails with "unrecognized intrinsic subprogram"

[Ahmad Bamba via Gcc-help <gcc-help@xxxxxxxxxxx>]

Hello gcc-help,

I am trying to build a C, C++, and Ada cross compiler off of the
release/gcc-14 branch, following this page's instructions:
https://gcc.gnu.org/install/
It seems to compile the C and C++ parts fine, but fails when building the
first Ada source files. The last output before the error is:

  gcc -c -g -O2      -gnatpg  -W -Wall -fno-PIE -nostdinc -I- -I.
-Iada/generated -Iada -I/home/ablinux/gcc/gcc/ada -Iada/libgnat
-I/home/ablinux/gcc/gcc/ada/libgnat -Iada/gcc-interface
-I/home/ablinux/gcc/gcc/ada/gcc-interface
/home/ablinux/gcc/gcc/ada/spark_xrefs.adb -o ada/spark_xrefs.o
  s-stoele.ads:87:13: unrecognized intrinsic subprogram
  make[2]: *** [/home/ablinux/gcc/gcc/ada/gcc-interface/Make-lang.in:166:
ada/spark_xrefs.o] Error 1
  make[2]: Leaving directory '/home/ablinux/objdir/gcc'
  make[1]: *** [Makefile:4704: all-gcc] Error 2
  make[1]: Leaving directory '/home/ablinux/objdir'
  make: *** [Makefile:1064: all] Error 2

It seems like, somehow, during configuration, the list of implemented
intrinsic subprograms don't match? I unfortunately haven't seen this error
anywhere else and I'm not sure what I could do to get the available
intrinsic subprograms to generate properly if that is indeed the issue. And
unfortunately, it doesn't say which intrinsic subprogram is the issue.
My configuration command was:

  bash ~/gcc/configure --target=arm-eabi --prefix=/opt/gcc-arm-toolchain
--enable-languages=ada,c,c++ --enable-libada

While arm gnat cross compilers are available to download, arm may not be
the only platform I cross-compile for. I have other reasons to want to
build from source as well.
My objdir (~/objdir) and sourcedir (~/gcc) are separate, unnested
directories as recommended.
My system details are:

I installed my host gcc-11 and gnat-11 via the Ubuntu package manager.
Although I am trying to build gcc-14, I've had this happen swapping over to
the gcc-13 and gcc-12 branches. When I invoke a parallel build, I notice
other Ada source files failing to compile as well.

Thank you.
