package/gdb: fix gnulib issue with musl and uClibc toolchains

Browse Source 
Starting with gdb 7.11, the bundled gnulib want to use rpl_gettimeofday
(gettimeofday replacement) due bad guessing when cross-compiling with musl
and uClibc toolchains. Instead of patching gnulib configure script to fix
the test, use gl_cv_func_gettimeofday_clobber=no to not use rpl_gettimeofday.

Thanks to Thomas Petazzoni to suggest this patch.
