  Ideally, the commit message should explain why it should be placed in 
LIBS instead of LDFLAGS.

  This is a non-Posix bashism. You'd need something like

EXTRA_LIBS=${EXTRA_LIBS:-}

  However, why not just use the LIBS environment variable? Oh, looks like 
the Makefile.in is broken as well and should be patched to use @LIBS@ 
(which also removes the need for this EXTRA_LIBS hack).

  Is this project still maintained upstream? If not, don't bother 
creating upstreamable patches. If it is still maintained, a proper 
upstreamable patch could change configure.in to use PKG_CHECK_MODULES for 
libpcreposix.

  Regards,
  Arnout
