make install fails as it tries to write in /tmp

[Thibaut Appel]

Dear Viktor,

I did try to change that hard-coded /tmp.

make install now fails because of

link 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so 
-> 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so.1.1
install libcrypto.so -> 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so
install libcrypto.so.1.1 -> 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so
ar: 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so: 
file format not recognized
ar: 
/rds/general/user/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h/lib/libcrypto.so.new: 
file format not recognized
make: *** [install_dev] Error 1

and I have

$ perl configdata.pm -c

Command line (with current working directory = .):

     /usr/bin/perl ./Configure linux-x86_64 
--prefix=/rds/general/user/ta3616/home/.linuxbrew/Cellar/openssl at 1.1/1.1.1h

Perl information:

     /usr/bin/perl
     5.16.3 for x86_64-linux-thread-multi

It seems https://github.com/openssl/openssl/issues/6641 was about the 
same issue. I found out that my Text::Template is 1.45. Maybe that's the 
problem
