A quick follow up....

There appears to be at least two problems. First, Git's configure does
not report errors. Rather, it silently swallows them. (It silently
swallowed an error with the PCRE library, too).

Second, cURL appears to translate `-arch ppc` into `-arch ppc7400`. So
the 8 or so dependent libraries look like:

$ file /usr/local/lib/libcrypto.a
/usr/local/lib/libcrypto.a: Mach-O universal binary with 2 architectures
/usr/local/lib/libcrypto.a (for architecture ppc): current ar
archive random library
/usr/local/lib/libcrypto.a (for architecture ppc64): current ar
archive random library

But cURL looks like:

$ file /usr/local/lib/libcurl.a
/usr/local/lib/libcurl.a: Mach-O universal binary with 2 architectures
/usr/local/lib/libcurl.a (for architecture ppc7400): current ar
archive random library
/usr/local/lib/libcurl.a (for architecture ppc64): current ar
archive random library

I verified its not my setting:

export CFLAGS="-arch ppc"
export LDFLAGS="-arch ppc"
./configure ...
make
$ lipo -info ./lib/.libs/libcurl.a
...
Non-fat file: ./lib/.libs/libcurl.a is architecture: ppc7400
