gdk-pixbuf2 does't build for ppc on 10.6.8 (Rosetta): cannot find linker (meson build system issue)

[barracuda156]

Same problem as here: ​https://trac.macports.org/ticket/64525

Same solution: configure.compiler=macports-gcc-7 build_arch="ppc" makes it build successfully.

Sergey-Fedorovs-Mac-mini:~ svacchanda$ port -v installed gdk-pixbuf2
The following ports are currently installed:
  gdk-pixbuf2 @2.42.2_2+x11 (active) requested_variants='' platform='darwin 10' archs='ppc' date='2022-01-26T16:15:41+0800'

Looks like meson build system is essentially broken in case of 10.6.8 Rosetta.
