gdb/testsuite: re-compile entry-value-typedef .S files with -fPIE
As Luis pointed out here [1], the AArch64 variant of the test doesn't
work on systems that use PIE by default. For example, on this Debian
11:
$ make check TESTS="gdb.dwarf2/entry-value-typedef.exp"
gdb compile failed, /usr/bin/ld: /tmp/ccJE8ZSr.o: relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol `_ZNSsD1Ev@@GLIBCXX_3.4' which may bind externally can not be used when making a shared object; recompile with -fPIC
/usr/bin/ld: /tmp/ccJE8ZSr.o(.text+0x38): unresolvable R_AARCH64_ADR_PREL_PG_HI21 relocation against symbol `_ZNSsD1Ev@@GLIBCXX_3.4'
This is because entry-value-typedef-aarch64.S was generated on an old
system that does not generate position-independent code by default, but
the system the test runs on tries to link the test executable as
position-independent. Fix this by regenerating the same binary on the
same system as the original one, but with -fPIE this time. Do the same
for the amd64 binary, although this one was already position-independent
so the generated code doesn't change.
With this patch applied, the test passes on the Debian 11 AArch64
system.
