Hi,
The getline.m4 causes trouble in relocatable.c if, during cross-compilation,
it defines getline to rpl_getline _even_ on glibc2 systems. A link
error occurs because relocatable.c is not prepared to need the getline.o
replacement module.
The fix is to make the getline.m4 test less pessimistic.

* getline.m4 (AM_FUNC_GETLINE): When cross-compiling, assume that
getline works on glibc2 systems. Needed to avoid trouble in
relocatable.c.
