Building 8.12.0 from source failes

[mschroeder-fzj]

I did this

I am building a static binary version of curl that tries to be as small as possible with only http required.
For that I am using debian:stable-slim as Contianer image with these packages installed:
build-essential clang perl gcc musl-dev libwolfssl-dev cmake autoconf automake libtool curl tar

Build command:

export CC=clang
autoreconf -fi

make -j4 V=1 LDFLAGS="-static -all-static" CFLAGS="-Os"

I expected the following

A static binary should be build.

Instead it failes with:

+ make -j4 V=1 LDFLAGS=-static -all-static CFLAGS=-Os

For curl Versions 8.8.0 until 8.11.1 it worked just fine.
