[Bug target/43727] New: undefined reference to `_restgpr_30_x'

[marcus at jet dot franken dot de]

In -Os mode I see undefined references to _restgpr_* _savefpr_* and similar
functions.

Michael Matz sees libgcc.a not added to the linkline in this mode.

testcase:

g++ -Os -shared -o libhello.so -Wl,-z,defs -fPIC hello.c
/tmp/cc8oo25Z.o: In function `hello()':
hello.c:(.text+0x30): undefined reference to `_restgpr_30_x'
collect2: ld returned 1 exit status
