libstdc++: Do not use isatty on avr [PR115482]

Browse source 
avrlibc has an incomplete unistd.h that doesn't have isatty.
So building libstdc++ fails when compiling c++23/print.cc.
As a workaround I added a check for AVR.

libstdc++-v3/ChangeLog:

	PR libstdc++/115482
	* src/c++23/print.cc (__open_terminal) [__AVR__]: Do not use
	isatty.

(cherry picked from commit 8439405e38c56b774cf3c65bdafae5f9e11d470a)
