It seems glibc library changed in 2021 causing a lot of issues like this, this, this and so on.
Here they talk about this ubuntu patch for m4 1.4.18 (debian\patches\04-fix-sigstksz.patch):
Updated m4:
M4_VERSION = 1.4.19
sha256 63aede5c6d33b6d9b13511cd0be2cac046f2e70fd0a07aa9573a04a82783af96 m4-1.4.19.tar.xz
sha256 3972dc9744f6499f0f9b2dbf76696f2ae7ad8af9b23dde66d6af86c9dfb36986 COPYING
Updated fakeroot (also fails due glibc):
FAKEROOT_VERSION = 1.28
FAKEROOT_SOURCE = fakeroot_$(FAKEROOT_VERSION).orig.tar.gz
FAKEROOT_SITE = http://ftp.debian.org/debian/pool/main/f/fakeroot/
sha256 56d405e36ff685f83879be08fdd654255ab9aa38632b4605a98e896ad63990c2 fakeroot_1.28.orig.tar.gz
sha256 fc82ca8b6fdb18d4e3e85cfd8ab58d1bcd3f1b29abe782895abd91d64763f8e7 COPYING
Updated autoconf (Needed by newer fakeroot):
AUTOCONF_VERSION = 2.71
sha256 f14c83cfebcc9427f2c3cea7258bd90df972d92eb26752da4ddad81c87a0faa4 autoconf-2.71.tar.xz

Still failing...
For now, don't update to Ubuntu 21. Ubuntu LTS 20.04.4 has glibc-2.3.1, building works.
