The 'gl_api' meson option was left at its 'auto' default, so the
GL plugin probed for desktop OpenGL. OpenWrt's Mesa is built with
-Dglx=disabled and -Dglvnd=disabled on every target, so it ships
no linkable desktop-GL library (no libGL.so, no gl.pc) - desktop
GL is only reachable through EGL. With nothing to satisfy the
probe in the sysroot, meson's cc.find_library('GL') fallback
escaped into the build host's /usr/lib and, on a host that has a
desktop libGL installed, put that foreign library on the link
line, breaking the cross link with:
mold: fatal: /usr/lib/libGL.so: incompatible file type:
riscv64 is expected but got x86_64
Pin -Dgl_api=gles2 and -Dgl_platform=egl to match what Mesa
actually provides (libGLESv2 + libEGL). This is correct on every
target, including x86_64: the desktop-GL link path was never
functional on OpenWrt and only ever "succeeded" by picking up a
host library.
