support build on Amazon Linux(or centos, redhat linux)

thought this should be quite similar to build on Ubuntu, tried for hours but failed

my efforts include:

• install build prerequisites by: sudo yum groupinstall "Development Tools"
• upgrade cmake by: pip3 install cmake --upgrade
• create symbolic link for ninjia-build by: ln -s /usr/bin/ninja-build /usr/bin/ninja
• install nss by: sudo yum install libnss3.so libnssutil3.so
• add search path(/usr/lib/) for lib nss in curl-impersonate.patch#:

  -+          search_paths="/usr/lib/$host /usr/lib/$host/nss"
  ++          search_paths="/usr/lib/ /usr/lib/$host /usr/lib/$host/nss"
  

still failed when doing make firefox-build, the log suggested failed linking NSS:

configure: WARNING: Using hard-wired libraries and compilation flags for NSS.
checking if libnssckbi is in a non-standard location... /usr/lib
checking for SSL_VersionRangeSet in -lnss_static... no
configure: error: Failed linking NSS statically

the related log in ./curl-7.81.0/config.log is:

any help is appreciated

I’ve added the necessary fixes to make it work on Amazon Linux & Fedora.

Seems like the actual issue is with linking with libbrotli, not NSS. Do you have .a files in /home/ec2-user/apps/curl-impersonate/build/brotli-1.0.9/out/installed/lib? The curl build looks for libbrotlidec-static.a and libbrotlicommon-static.a.
