yes, or I could just as easily hardcode
FOO_LIBS="-L/usr/local/lib -lfoo -lbar"
in configure.

so now, I'm not using pkg-config at all.  it's not uncommon to see
such things.  how would libtool deal with that?

how is that a conflict?  would the case above be an irreconcilable
conflict?

libtool already scrutinizes the command line for relevant flags.
if libtool is so infinitely better than anything else at building
libraries, then why can't it simply drop irrelevant/duplicated
flags, and add the ones it needs?
