[PATCH] Fix PCH failures on SPARC

[Eric Botcazou]

Hi,

As previously discussed, several PCH testcases fail on SPARC because of 
duplicated labels emitted by the stabs debugging code. The attached patch 
fixes them, by exposing the previously hidden static variables and marking 
them with GTY(()).

Bootstrapped/regtested on sparc-sun-solaris2.6 (c,c++,objc,f77 mainline), the 
remaining C PCH testcases being fixed and the libstdc++-v3 testsuite now 
producing significative results. There are 3 remaining C++ PCH failures.

Tested by successfully cross-compiling to the following targets

alpha-unknown-linux-gnu
avr-unknown-elf
hppa1.1-hp-hpux11
i386-sequent-ptx4
i960-unknown-coff
m32r-unknown-elf
m68k-hp-hpux
mcore-unknown-pe
mips-unknown-linux-gnu
mmix-knuth-mmixware
powerpc64-unknown-linux-gnu
rs6000-ibm-aix4.1
sh-unknown-linux-gnu
sparc64-unknown-aout

and unsuccessfully, but for reasons unrelated to the patch, to

rs6000-unknown-lynxos
sparc-tti-bsd
