FreeBSD port (54): configure and -D_LIBC_REENTRANT

[Bruno Haible]

Hi,

linuxthreads/sysdeps/unix/sysv/linux/configure
adds -D_LIBC_REENTRANT to the DEFINES. For FreeBSD I need to copy this to
linuxthreads/sysdeps/unix/bsd/bsd4.4/freebsd/configure.
But _LIBC_REENTRANT is needed on any platform using linuxthreads, be it
Linux, FreeBSD or any other. So here is a generalization of this configure
bit.


ChangeLog:
2002-09-17  Bruno Haible  <bruno@clisp.org>

	* sysdeps/pthread/configure: New file, moved here from
	linuxthreads/sysdeps/unix/sysv/linux/configure.

linuxthreads/ChangeLog:
2002-09-17  Bruno Haible  <bruno@clisp.org>

	* sysdeps/unix/sysv/linux/configure: Remove file.

rm -f linuxthreads/sysdeps/unix/sysv/linux/configure
