[Fontconfig] libiconv detection seems convoluted

[Akira TAGOH]

I've tried to use AM_ICONV instead, indeed, it may works as you
expected and actually it does. however it also introduces the RPATH
issue too. need to think about it more. just FYI.

There are a bunch of special-purpose --with-libiconv* flags, but there doesn't seem to be an easy way to handle my situation. If I understand the if/elif spaghetti, I need to declare an explicit libiconv prefix or includes directory in order for libiconv_cflags to be set, which is the only way to trigger libiconv_libs getting set. Or else I need to pass LDFLAGS=-liconv to the whole build process.

For portability, hand-coding seems fragile, and ease of use ("behaves like other packages that use libiconv") also suffers. For example, libiconv's iconv.m4 has a AM_ICONV function.
