[testsuite] Fix 32-bit gcc.dg/lto/pr55525 with Sun ld

[Rainer Orth]

gcc.dg/lto/pr55525 currently FAILs on Solaris with Sun ld for the 32-bit
multilib:

FAIL: gcc.dg/lto/pr55525 c_lto_pr55525_0.o-c_lto_pr55525_1.o link,  -flto -w 
UNRESOLVED: gcc.dg/lto/pr55525 c_lto_pr55525_0.o-c_lto_pr55525_1.o execute  
-flto -w 

ld: fatal: symbol 's' has differing sizes:
        (file c_lto_pr55525_0.o value=0x8; file c_lto_pr55525_1.o value=0x4);
        tentative symbol cannot override defined symbol of smaller size

The following patch (from Richi) fixes this.

Tested with the appropriate runtest invocation on i386-pc-solaris2.10
and x86_64-unknown-linux-gnu (both multilibs each), installed on
mainline as approved in the PR.

        * gcc.dg/lto/pr55525_0.c (s): Size like char *.
