Can't seem to get Windows x86 binaries to build

Question

Hello! As the title says, I can't seem to get LWJGL to build for x86 Windows with x64 toolchain.
My steps:

set PATH_OLD=%PATH%
set LWJGL_BUILD_ARCH=x86
set LWJGL_BUILD_OFFLINE=true
set JAVA_HOME=F:\.jdks\jdk-17.0.2 // 64 bit
set PATH=F:\.jdks\jdk-17.0.2\bin;%PATH_OLD%
set VSCMD_SKIP_SENDTELEMETRY=true
vcvarsall x86

set JAVA_HOME=F:\.jdks\jdk-17.0.2-x86 // 32 bit
set PATH=F:\.jdks\jdk-17.0.2-x86\bin;%PATH_OLD%
ant compile-native

Problem: libffi does not seem to get picked up for some reason:
