Older objcopy mangles bootloader built with musl

[JonathonReinhart]

Long stories (#198, #203) very short: objcopy on CentOS 7 mangles the program headers of a bootloader built with musl-gcc on Debian bullseye.

Built on: Debian bulseye, gcc 10.2.1, musl-tools 1.2.2-1

Distro	objcopy	Status
CentOS 7	2.27-44.base.el7	❌ Fail
Debian 9	2.28	❌ Fail
Ubuntu 18.04	2.30	❌ Fail
Debian 10	2.31.1	❌ Fail
Debian 11	2.35.2	✔️ OK

Workaround

Don't install the published wheels:

pip install --no-binary=staticx staticx

Just for your information.
The install of staticx from source worked to solve segfaulting binaries generated within docker container based on official python:3 image.
To get the installation running I had to install scons within the container first.
