You need to call configure with --with-libgcc
Binaries compiled with that tcc will crash immediately unless you apply
this patch:

This is not an eabi arm debian image, so TCC_ARM_EABI has not been
defined. If it was, there would be a /lib/ld-linux.so.3 instead of
/lib/ld-linux.so.2.
/proc/cpuinfo mentiones VFP floating point support, so TCC_ARM_VFP
is defined. But looking at the code generated by gcc, it should not
be defined as libc will return values in FPA registers. There also
is an issue with double constants having their halves swapped when
this is defined incorrectly.
