Add condition based on file extension

[Puya]

Hi, is there a way to add a condition based on file extension in GYP? I tried this:
```
'cflags': [
  '-fPIC',
  '-Wall',
  '-W',
  '-Wno-unused-parameter',
  '-std=c++17',
],

'conditions': [
  [ 'RULE_INPUT_EXT == "c"', {
    'cflags!': [
      '-std=c++17',
    ],
  } ],
  ...
```
To no avail.

Hi, just use `cflags_cc` for C++ files.
