The following configure/make/make install worked just fine
$ ~/src/gcc-10.3.0/configure --target=avr --enable-languages=c,c++
--prefix=/home/saaadhu/install --disable-nls --disable-libssp
--with-dwarf2
I suspect fortran in --enable-languages is what is causing issues. Do
you really need gfortran? Also, does symlinking /usr/lib/avr to
/avr help?

LDFLAGS, CFLAGS etc.. are used when building the binary that runs on
the host (i.e xgcc in your example). I haven't tried building gcc
against avr-libc installed at a different prefix, but could you try
BOOT_LDFLAGS and see if it helps?

I haven't used that tool either. I'll try building gcc 10.3 from
scratch tonight and post the steps I used.

No, avr-libc is installed in /usr/lib/avr, but I have tried to add
LDFLAGS on configure command line without any success.
I have tried to build cross compiler with ct-ng also without any
success (from gcc 6.x to 11.x). Same error. ct-ng builds its own
avr-libc and doesn't use system avr-libc.

Did you try building and installing avr-libc also at the same --prefix location?
