Build process relies on vcpkg glibc binaries

[apprehensions]

I am on a Linux musl-based distribution, and building Ladybird requires running a binary from Microsoft which is linked against glibc; it causes the following build errors:

$ ./Meta/ladybird.sh run ladybird

A quick check at the binary:

$ ldd /home/sewn/src/ladybird/Toolchain/Tarballs/vcpkg/vcpkg

Based on https://github.com/microsoft/vcpkg/blob/master/scripts/bootstrap.sh it looks like Toolchain/BuildVcpkg.sh needs to conditionally pass -musl

More glibc binaries.

Similar error on Ubuntu 23.10 in WSL2

[ADKaster]

If modifying our BuildVcpkg.sh script to add --musl does not produce a working install on Alpine without glibc compat libraries, then that is a bug with upstream vcpkg.

Is it the case that removing Toolchain/Tarballs, Toolchain/Local, and Toolchain/Build, modifying Toolchain/BuildVcpkg.sh to pass --musl to the vcpkg bootstrap script, and re-running the build still produces binaries that require glibc symbols?

See the my last comment before this one @ADKaster

Noticed this

cat /home/stefano/ladybird/Toolchain/Tarballs/vcpkg/buildtrees/icu/config-x64-linux-dbg-err.log configure: WARNING: unrecognized options: --disable-silent-rules configure: error: 'autoconf-archive' is missing

I installed the package with apt and now it is moving along, I update this comment when the compilation ends

EDIT: Compiled successfully, I forgot to set the env variable so I run like this and it works (created the tmp directory under the user and set permission 0700)

XDG_RUNTIME_DIR=/var/tmp/ladybird ./Meta/ladybird.sh run ladybird
