--with-host-libstdcxx="-L/usr/lib -lstdc++" fails earlier:

If I rerun the failing gcc command removing manually the "-L/usr/lib" and
keeping the "-lstdc++"
it works and the resulting cc1-dummy is as follows:
gue...@gcc17:~/build-ppl/gcc$ ldd ./cc1-dummy
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00002aaaaabc3000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00002aaaaadc1000)
libc.so.6 => /lib/libc.so.6 (0x00002aaaaaecf000)
libm.so.6 => /lib/libm.so.6 (0x00002aaaab10c000)
/lib64/ld-linux-x86-64.so.2 (0x00002aaaaaaab000)
May be we need something for stage1 and a different thing later on?
Thanks in advance for your help,
Laurent
