What happens if you have multiple of such occurrences? You will pass
LIBS='-lfoo' LIBS='-lbar', etc.

Shouldn't we instead do:

PHP_LIBS += -lpthread

and then later, a single PHP_CONF_ENV += LIBS=$(PHP_LIBS)

Also, it's a shame unixodbc doesn't use pkg-config. It installs its own
odbc-config, but I guess it's compiled for the target, and most likely
returns results that are inappropriate for cross compilation.
