Update of /var/cvs/uClibc/libc/sysdeps/linux/sh
In directory winder:/tmp/cvs-serv5260/libc/sysdeps/linux/sh
Modified Files:
Makefile crt0.S
Log Message:
Based on discussions with Stefan Allius, change it so that we always
build a crt0.o and a crt1.o. crt1.o will support ctors and dtors if
such support is enabled. One more gratuitous toolchain support issue
is thereby removed...
