Update.

* Makeconfig [!build-static]: Link `static' binaries with libc_pic.a.
Still need *FLAGS-.o because we still sometimes build .o files.
* db2/Makefile: Don't build libndbm.a if !build-static.
1998-04-16 07:42 Geoff Keating <geoffk@ozemail.com.au>
* configure.in: New test for broken gcc on PowerPC.
* sysdeps/powerpc/atomicity.h: Use result of test.
* linuxthreads/sysdeps/powerpc/pt-machine.h: Use result of test.
* math/libm-test.c: Update many of the epsilon to match actual
performance.
* sysdeps/libm-ieee754/e_exp.c: Reduce the number of branches.
* sysdeps/libm-ieee754/e_expf.c: Likewise.
* sysdeps/libm-ieee754/s_exp2.c: Likewise.
* sysdeps/libm-ieee754/s_exp2f.c: Likewise.
* sysdeps/libm-ieee754/e_pow.c: Correct typo.
* sysdeps/powerpc/elf/libc-start.c: New file.
* sysdeps/powerpc/elf/start.S: New file, use libc-start.
* sysdeps/powerpc/elf/start.c: Delete.
* sysdeps/unix/sysv/linux/powerpc/Dist: Remove syscall.h
* sysdeps/unix/sysv/linux/powerpc/syscall.h: Delete. It was unused.
* sysdeps/unix/sysv/linux/powerpc/dl-sysdep.c: Correct previous
few patches.
