This is a side-effect of our fake installation for gprofng testing:
>>  # Make a temporary install dir to run gprofng from, and point at it
>>  remote_exec host "sh -c \"rm -rf tmpdir; mkdir -p tmpdir; $MAKE -C .. 
>> install-gprofng 
>>  program_transform_name= DESTDIR=`pwd`/tmpdir/root\""

 I will fix this and will not run '$MAKE install-gprofng'.


But why is libopcodes.la rebuilt when I run `make install` ?

To reproduce:
% ../binutils-gdb.git/configure --prefix=`pwd`/INSTALL --with-system-zlib
--enable-shared
--disable-{gdb,gdbserver,libbacktrace,libdecnumber,readline,sim}
% make -j 100
% make install
...
make[4]: Nothing to be done for 'install-exec-am'.
 /bin/mkdir -p '/data2/vmezents/bld/INSTALL/include'
 /bin/install -c -m 644 ../../binutils-gdb.git/opcodes/../include/dis-asm.h
'/data2/vmezents/bld/INSTALL/include'
 /bin/mkdir -p '/data2/vmezents/bld/INSTALL/lib'
 /bin/sh ./libtool   --mode=install /bin/install -c   libopcodes.la
'/data2/vmezents/bld/INSTALL/lib'
libtool: install: warning: relinking `libopcodes.la'
                  ^^^^^^^^^^^^^^^^^^
                  | Why ? There were no changes.


libtool: install: (cd /data2/vmezents/bld/opcodes; /bin/sh
/data2/vmezents/bld/opcodes/libtool  --silent --tag CC --mode=relink gcc 
  -W -Wall -Wstrict-prototypes -Wmissing-prototypes -Wshadow 
  -Wstack-usage=262144 -Werror -g -O2 -release 2.39.50.20221006 
  -o libopcodes.la 
  -rpath /data2/vmezents/bld/INSTALL/lib dis-buf.lo disassemble.lo 
  dis-init.lo i386-dis.lo i386-opc.lo ../bfd/libbfd.la 
  -L/data2/vmezents/bld/opcodes/../libiberty/pic -liberty 
  -Wl,-lc,--as-needed,-lm,--no-as-needed )
....

We see libopcodes.la was rebuilt.
