Failed sanity check at LFS 5.7.Glibc-2.29 – CentOS

I want to cross-compile LFS on CentOS v. 7.6.1810 with no sudo rights (I want to customize my environment on server). One problem is that globally a lot of packages are outdated (for instance, python 2.7, gcc 4.8.5, gmake 3.82).

In this setting I started from the 4-th chapter of LFS and changed everywhere PATH from /tools to /path/to/my/folder/tools (I believe I did it accurately enough). It all went well until chapter 5.7. First, Glibc wanted to have newer python and gmake.
Therefore I followed 5.27.1 and 5.30.1 chapters.

After this, everything compiles well, and I was stopped on the sanity check step. I executed it from the sources/glibc/build folder, and got an error:

> echo 'int main(){}' > dummy.c
> $LFS_TGT-gcc dummy.c

I checked /path/to/my/folder/tools/lib/, and all wanted files (crt1.o, crti.o, libc.so.6, libc_nonshared.a, ld-linux-x86-64.so.2) are there.

I tried providing symbolic links to files and it worked for crt1.o and crti.o but not for the others.

UPDATE 1 Now I reinstalled older version LFS (8.1), so that I had all prerequisites fulfilled from the start. Once again I started from the 4-th chapter and no errors rose until the notorious check. The suggestion from Tim was helpful in the way the system was not ruined, but segmentation error did not allow a.out to be created:

> echo 'int main(){}' > dummy.c
> LD_LIBRARY_PATH=/path/to/my/folder/tools/lib $LFS_TGT-gcc dummy.c
Segmentation fault (core dumped)
> readelf -l a.out | grep ': /path/to/my/folder/tools'
readelf: a.out: Error: No such file

Inspired by the similar issue LFS 7.2 glibc-2.16.0 make error and tried to change LD_LIBRARY_PATH accordingly. It does not seem to work.

UPDATE 2 I once again reinstalled LFS (8.1), but this time I followed steps described in this issue. Also, I used -Xlinker --verbose solution described in the comments here to inspect ld logs. Now it seems, that maybe it cannot open the mentioned libraries. Still not working, but log seems to have changed a bit.

Can you please give a suggestion, how to deal with this nasty ld problem. I know that it is not good to skip LFS steps. Unfortunately, I have no way to fix this, but I want to upgrade my local environment as much as possible. Thank you!
