- Subject: Fix configure test for ELF in BFD for static libraries
GDB has a configure test for ELF support in BFD. This is a link test,
linking with $LIBS -lbfd -liberty $intl. If using zlib, this means -lz
comes before -lbfd, and with static libraries that means -lz will not be
used to resolve symbols needed by -lbfd - so the configure test fails when
BFD requires zlib and a static zlib is being used.
This patch puts the previous $LIBS setting after the extra libraries being
tested rather than before, so that -lz can be used to resolve symbols
needed by -lbfd. OK to commit?

* configure.ac: Put old value of $LIBS after -lbfd -liberty $intl
in BFD ELF check.
* configure: Regenerate.
