Hello,
II tried compiling avr-gcc (AVR 8-bit target) with libstdcxx support,
and even if I set the configure parameters to be "disable-shared" and
"enable-static", the "configure" step fails because it checks for
dlopen() support in avrlibc (which doesn't exist).
I see that in the newlib case, the failing step is skipped, so I've
just added branch to the condition, to skip the same check for
avrlibc.
Please double-check this patch, as it's my first commit to the GCC
project, and I had to manually adjust a couple of things for the
regeneration step to work out.
Thank you,
Adrian Stratulat
