После этого я делаю это как tar.gz-файл и копирую на устройство и не согласую его.
На устройстве:

valgrind: Fatal error at startup: a function redirection
valgrind: which is mandatory for this platform-tool combination
valgrind: cannot be set up. Details of the redirection are:
valgrind:
valgrind: A must-be-redirected function
valgrind: whose name matches the pattern: strlen
valgrind: in an object with soname matching: ld.so.1
valgrind: was not found whilst processing
valgrind: symbols from the object with soname: ld.so.1
valgrind:
valgrind: Possible fixes: (1, short term): install glibc's debuginfo
valgrind: package on this machine. (2, longer term): ask the packagers
valgrind: for your Linux distribution to please in future ship a non-
valgrind: stripped ld.so (or whatever the dynamic linker .so is called)
valgrind: that exports the above-named function using the standard
valgrind: calling conventions for this platform. The package you need
valgrind: to install for fix (1) is called
valgrind:
valgrind: On Debian, Ubuntu: libc6-dbg
valgrind: On SuSE, openSuSE, Fedora, RHEL: glibc-debuginfo
valgrind:
valgrind: Note that if you are debugging a 32 bit process on a
valgrind: 64 bit system, you will need a corresponding 32 bit debuginfo
valgrind: package (e.g. libc6-dbg:i386).
valgrind:
valgrind: Cannot continue -- exiting now. Sorry.
Я добавил некоторую проверку в файл m_redir.c и скомпилировал и загрузил valgrind.

disInstr(ppc): found an AltiVec or an e500 instruction 0x13C17320
that can't be handled by Valgrind. If this instruction is an
Altivec instruction, Valgrind must be run on a host that supportsAltiVec instructions. If the application was compiled for e500, then
unfortunately Valgrind does not yet support e500 instructions.
==1836== valgrind: Unrecognised instruction at address 0x400df78.
==1836== at 0x400DF78: ??? (in /lib/ld-2.6.so)
==1836== Your program just tried to execute an instruction that Valgrind
==1836== did not recognise. There are two possible reasons for this.
==1836== 1. Your program has a bug and erroneously jumped to a non-code
==1836== location. If you are running Memcheck and you just saw a
==1836== warning about a bad jump, it's probably your program's fault.
==1836== 2. The instruction is legitimate but Valgrind doesn't handle it,
==1836== i.e. it's Valgrind's fault. If you think this is the case or
==1836== you are not sure, please let us know and we'll try to fix it.
==1836== Either way, Valgrind will now raise a SIGILL signal which will
==1836== probably kill your program.

Вы, видимо, используете Ubuntu 17.04 и хотите использовать valgrind версию 3.13, доступную в Ubuntu 17.10. Проще всего было бы перейти на Ubuntu 17.10 и установить valgrind из репозиториев Ubuntu по умолчанию. Ubuntu 17.04 будет концом жизни в течение месяца до этого февраля.
