Hi,

The new meson setup is great and makes cross compiling much easier than with the autotools build system!

However meson install fails because it tries to execute the just built fc-cache, which is built for the target platform not the build host.

I'm building with master as of today, and meson 0.55.3.

Here's the reproduction steps:

[jbit@hina]/src/fontconfig$ git rev-parse HEAD
abc723366d692df2210346e0d4d3c5686e22c3ef

[jbit@hina]/src/fontconfig$ meson --version
0.55.3

[jbit@hina]/src/fontconfig$ mkdir build/ && cd build/

[jbit@hina]/src/fontconfig/build$ cat << EOF > cross.conf
[host_machine]
system = 'linux'
cpu_family = 'aarch64'
cpu = 'cortex-a53'
endian = 'little'
[properties]
sys_root          = '/sysroot/aarch64'
pkg_config_libdir = '/sysroot/aarch64/usr/lib/pkgconfig'
[binaries]
c         = 'aarch64-linux-musl-gcc'
cpp       = 'aarch64-linux-musl-g++'
ar        = 'aarch64-linux-musl-ar'
ld        = 'aarch64-linux-musl-ld'
objcopy   = 'aarch64-linux-musl-objcopy'
strip     = 'aarch64-linux-musl-strip'
pkgconfig = 'pkg-config'
EOF

I have a fix for this, and will open a Merge Request, I just wanted to make sure it's in the issue tracker too.

Cheers
