Hi, since 2.16, glibc dropped support for any binary format other than ELF; the removal of the 'elf' variable causes libpthread.so to not link, since ld.so is not passed to the linking line. The attached patch defines elf to yes if not defined, allowing to keep compatibility also with glibc < 2.16.
Also, I'm slightly in doubt about the ChangeLog snippet, not totally sure about how to write it properly in this case. -- Pino Toscano
