patch 2/2 causes bootstrap failures on powerpc:
a-chahan.o: In function `ada__characters__handling__is_iso_646__2':
/home/segher/build/tot-master/gcc/ada/rts_32/a-chahan.adb:354:(.text+0x22a):
relocation truncated to fit: R_PPC_REL16 against undefined symbol `.LCL8'+e
a-chahan.o: In function `ada__characters__handling__is_string':
/home/segher/build/tot-master/gcc/ada/rts_32/a-chahan.adb:442:(.text+0x49a):
additional relocation overflows omitted from the output

(this is while building the 32-bit libgnat-7.so; that uses -fPIC).
32-bit -fPIC generates code a la

.globl f
.LCL0:
.long .LCTOC1-.LCF0
.type f, @function
f:
stwu 1,-16(1)
mflr 0
bcl 20,31,.LCF0
.LCF0:

and in the failing cases that .LCL0 went missing in action.
