Issue 1:
After downloading the latest version of Deno 1.7.3 from GitHub, the binary throws the following error under Debain 10 64Bit:

./deno: /lib/x86_64-linux-gnu/libm.so.6: version GLIBC_2.29' not found (required by ./deno)

uname output:

Linux 4.19.0-14-amd64 #1 SMP Debian 4.19.171-2 (2021-01-30) x86_64 GNU/Linux

The binary is, however, functional under Ubuntu 20.04 64Bit.

Seems like my system is missing GLIBC_2.29?
