-------------------------------------------------+-------------------------
 I have tried building `ruby27` and `ruby30` for ppc, they fail on
 configure with one test. The following patch fixes configure, and then
 both build through completion (example for ruby30):

 {{{

 }}}

 Elsewhere the source code has references to ppc and powerpc-darwin, so
 this test looks rather arbitrary.
 Everything looks okay then:

 {{{
 36-109% file /opt/local/bin/ruby3.0
 /opt/local/bin/ruby3.0: Mach-O executable ppc
 36-109% /opt/local/bin/ruby3.0 -v
 ruby 3.0.3p157 (2021-11-24 revision 3fb7d2cadc) [ppc-darwin10]
 36-109% port -v installed ruby30
 The following ports are currently installed:
   ruby30 @3.0.3_1 (active) requested_variants='' platform='darwin 10'
 archs='ppc' date='2022-03-30T04:04:37+0800'
 }}}

 However when I try building dependencies with either of newly installed
 ruby versions, compilation freezes. No error is given, process just hangs
 indefinitely with 100% on one core but apparently doing nothing. (I had a
 similar freeze with recent gobject/vala-related dependencies like gexiv2.)

 What did I miss?
