cross/avr-gcc: Update to 10.3.0nb1

Deleting the unwanted libcc1 after installation failed on some OS (because
they use non-standard paths for the library directory). The configure option
"--disable-libcc1" is now used instead.
Bump PKGREVISION because this change removes 2 plugins from the PLIST too.

Mention the C++ compiler in DESCR again.
