compiler.sizeof() returns -1 with emscripten

Describe the bug When doing a cross-build with emscripten, compiler.sizeof() returns -1 for any type passed.

To Reproduce

Build file used: meson.build

project(
  'myexec',
  'c'
)

cc = meson.get_compiler ('c')

char_size = cc.sizeof('char')
short_size = cc.sizeof('short')
int_size = cc.sizeof('int')
voidp_size = cc.sizeof('void*')
long_size = cc.sizeof('long')

Cross-File used: emscripten.conf

[binaries]
c = 'emcc'
cpp = 'em++'
ld = 'wasm-ld'
ar = 'emar'
ranlib = 'emranlib'
make = 'emmake'
cmake = 'emcmake'

[host_machine]
system = 'emscripten'
cpu_family = 'wasm32'
cpu = 'wasm32'
endian = 'little'

[properties]
needs_exe_wrapper = true

Expected behavior Return the size of the types. E.g.:

Checking for size of "short" : 2
Checking for size of "int" : 4
Checking for size of "void*" : 4
