2019-02-26[libbacktrace] Fix btest-lto for older gccTom de Vries1-1/+2
With gcc 4.8.5, btest_lto ends up with a privatized name for the variable with name 'global': ... $ nm btest_lto | grep ' d ' | grep global 0000000000617150 d global.2530 ... which makes test5 fail: ... test5: unexpected syminfo name got global.2530 expected global ... Fix this failure by accepting this type of name as a valid name in btest_lto. 2019-02-26 Tom de Vries <tdevries@suse.de> * btest.c (test5): Allow global.* as minimal symbol name for global. From-SVN: r269217
