Thanks, Richard. I'm able to reproduce this. It's specific to 
meta-ide-support.

The setup looks fine:

$ meson setup --warnlevel 1 -Degl=no -Dglx=no -Dx11=false build
meson-wrapper: Running meson with setup options: " 
--cross-file=.../poky/build/tmp/sysroots/x86_64/usr/share/meson/arm-poky-linux-gnueabi-meson.cross 
--native-file=.../poky/build/tmp/sysroots/x86_64/usr/share/meson/meson.native 
"
The Meson build system
Version: 1.7.2
...

The KeyError appears because the build machine data is empty:

$ meson introspect -i --compilers build
{
     "host": {
         "c": {
             "id": "gcc",
             "exelist": [
                 "arm-poky-linux-gnueabi-gcc",
                 "-mthumb",
                 "-mfpu=neon",
                 "-mfloat-abi=hard",
                 "-mcpu=cortex-a15",
                 "-fstack-protector-strong",
                 "-O2",
                 "-D_FORTIFY_SOURCE=2",

                 "-D_TIME_BITS=64",
                 "-D_FILE_OFFSET_BITS=64",
                 "--sysroot=.../poky/build/tmp/sysroots/qemuarm"
             ],
             "linker_exelist": [
                 "arm-poky-linux-gnueabi-gcc",
                 "-mthumb",
                 "-mfpu=neon",
                 "-mfloat-abi=hard",
                 "-mcpu=cortex-a15",
                 "-fstack-protector-strong",
                 "-O2",
                 "-D_FORTIFY_SOURCE=2",
                 "-Wformat",
                 "-Wformat-security",
                 "-Werror=format-security",
                 "-D_TIME_BITS=64",
                 "-D_FILE_OFFSET_BITS=64",
                 "--sysroot=.../poky/build/tmp/sysroots/qemuarm"
             ],
             "file_suffixes": [
                 "c"
             ],
             "default_suffix": "c",
             "version": "14.2.0",
             "full_version": "arm-poky-linux-gnueabi-gcc (GCC) 14.2.0",
             "linker_id": "ld.bfd"
         }
     },
     "build": {}
}

I don't understand why. The meson.native file looks the same as for the 
standalone SDK case, and the meson machine data seems fine.

$ meson introspect -i --machines build/
{
     "host": {
         "system": "linux",
         "cpu_family": "arm",
         "cpu": "arm",
         "endian": "little",
         "kernel": null,
         "subsystem": null,
         "is_64_bit": false,
         "exe_suffix": "",
         "object_suffix": "o"
     },
     "build": {
         "system": "linux",
         "cpu_family": "x86_64",
         "cpu": "x86_64",
         "endian": "little",
         "kernel": "linux",
         "subsystem": "linux",
         "is_64_bit": true,
         "exe_suffix": "",
         "object_suffix": "o"
     },
     "target": {
         "system": "linux",
         "cpu_family": "arm",
         "cpu": "arm",
         "endian": "little",
         "kernel": null,
         "subsystem": null,
         "is_64_bit": false,
         "exe_suffix": "",
         "object_suffix": "o"
     }
}

I'm stuck.
