Fix --as-needed unneded usage

After compile, i get error on execute:

~ # faketime '2011-10-20 01:10:10' /bin/date
date: symbol lookup error: /usr/lib/faketime/libfaketime.so.1: undefined symbol: dlsym

because "--as-needed" added to default LD_FLAGS

Adding
"
pkg_setup() {
        append-ldflags $(no-as-needed)
}
"

fix these problem.



Before:
"
i686-pc-linux-gnu-gcc -o libfaketime.so.1 -Wl,-soname,libfaketime.so.1 -Wl,-O1 -Wl,--as-needed -shared -ldl -lm -lpthread faketime.o
i686-pc-linux-gnu-gcc -o libfaketimeMT.so.1 -Wl,-soname,libfaketimeMT.so.1 -Wl,-O1 -Wl,--as-needed -shared -ldl -lm -lpthread faketimeMT.o
"
After:
"
i686-pc-linux-gnu-gcc -o libfaketime.so.1 -Wl,-soname,libfaketime.so.1 -Wl,-O1 -Wl,--as-needed -Wl,--no-as-needed -shared -ldl -lm -lpthread faketime.o
i686-pc-linux-gnu-gcc -o libfaketimeMT.so.1 -Wl,-soname,libfaketimeMT.so.1 -Wl,-O1 -Wl,--as-needed -Wl,--no-as-needed -shared -ldl -lm -lpthread faketimeMT.o
"

I fixed the underlying linking order problem so building with --as-needed works fine with the latest revision.
