printf interception on 32-bit Linux/sparc64 doesn't work

[rorth]

With PR #107405, a couple of ASan tests that depend on printf interception FAIL on 32-bit Linux/sparc64:

  AddressSanitizer-sparc-linux :: TestCases/printf-2.c
  AddressSanitizer-sparc-linux :: TestCases/printf-3.c
  AddressSanitizer-sparc-linux :: TestCases/printf-4.c
  AddressSanitizer-sparc-linux :: TestCases/printf-5.c

  AddressSanitizer-sparc-linux-dynamic :: TestCases/printf-2.c
  AddressSanitizer-sparc-linux-dynamic :: TestCases/printf-3.c
  AddressSanitizer-sparc-linux-dynamic :: TestCases/printf-4.c
  AddressSanitizer-sparc-linux-dynamic :: TestCases/printf-5.c

  SanitizerCommon-asan-sparc-Linux :: Linux/unexpected_format_specifier_test.cpp

The issue is always the same: the interceptor doesn't run, which is no wonder given that the executables contains calls to __nldbl_print (no long double) instead of the expected __interceptor_printf.
