[Bug treelang/20604] New: treelang does not get passed -fPIC by default on *-darwin

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

You can tell that it does not get passed -fPIC by the following failure in the testsuite:
Executing on host: /Users/pinskia/src/new-fold/gcc/objdir/gcc/xgcc -B/Users/pinskia/src/new-fold/
gcc/objdir/gcc/ /Users/pinskia/src/new-fold/gcc/gcc/testsuite/treelang/execute/funccall.tree     -lm   
-o ./funccall.exe    (timeout = 300)
/usr/bin/ld: /var/tmp//ccbSoNBy.o has external relocation entries in non-writable section 
(__TEXT,__text) for symbols:^M
_abort^M
_exit^M
collect2: ld returned 1 exit status^M
compiler exited with status 1 
output is:
/usr/bin/ld: /var/tmp//ccbSoNBy.o has external relocation entries in non-writable section 
(__TEXT,__text) for symbols:^M_abort^M
_exit^M
collect2: ld returned 1 exit status^M

FAIL: treelang/execute/funccall.tree (test for excess errors)
Excess errors:
/usr/bin/ld: /var/tmp//ccbSoNBy.o has external relocation entries in non-writable section 
(__TEXT,__text) for symbols:
_abort
_exit

With -v I get:
 /Users/pinskia/src/new-fold/gcc/objdir/gcc/tree1 -quiet -dumpbase funccall.tree -v -o /var/tmp//
ccLOPtCF.s /Users/pinskia/src/new-fold/gcc/gcc/testsuite/treelang/execute/funccall.tree
