-----------------------+----------------------
 Changes in commit 990215fb0308d43a17285250e7ea5832d78d341b seem to prevent
 librsvg from building, the configure script fails at checking the C
 compiler. The compiler path is also passed as the first argument?
 The installation I'm working on is x86_64 emulated via Rosetta 2 on M1.

 {{{
 configure:4053: checking whether the C compiler works
 configure:4075: /usr/bin/clang /usr/bin/clang -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -arch x86_64

 x86_64 conftest.c  >&5
 ld: can't link with a main executable file '/usr/bin/clang' for
 architecture x86_64
 }}}
 Full log attached.

 After reverting to f81d9284291514bc66032866fb3451a1e7689dbc it builds
 without problems.
