Failed to compile the emacs latest git master version on Ubuntu 20.10.

[Hongyi Zhao]

On Ubuntu 20.10, I try to compile the emacs latest git master version
but meet the following error:

/usr/bin/ld: 
/usr/lib/gcc/x86_64-linux-gnu/10/../../../x86_64-linux-gnu/libm17n-core.a(mtext-wseg.o):
undefined reference to symbol 'th_brk@@LIBTHAI_0.1'
/usr/bin/ld: /lib/x86_64-linux-gnu/libthai.so.0: error adding symbols:
DSO missing from command line
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:655: temacs] Error 1
make[1]: Leaving directory '/home/werner/Public/editor/emacs/emacs.git/src'
make: *** [Makefile:424: src] Error 2

Any hints for fixing this problem?

Regards
