Extended Description

I am trying to make sac2c use a gcc linker option, but am not
having much luck. Here's what I tried:
sac2c time2code.sac -v1
/usr/local/lib/sac2c/18614/rt/host/seq/libsac.so: undefined reference to `SAC_HM_ShowDiagnostics'
collect2: error: ld returned 1 exit status
abort: System failed to execute shell command

compilation failed while Creating binary code.
This looks like the changed gcc linker behavior, where it no longer
does the "as-needed" inclusion of .so files.
I tried to fix this by creating /home/sac/.sac2crc, as follows:
target add_seq:
CFLAGS += " --Wl,--no-as-needed "
Compiling with this file produces the above result. I.e.,
it looks like the flags are NOT being used in the command line.
I know that the file IS being read, because if I spell the first
line as "xtarget" rather than "target", then the sac2c parser complains.
