since 64d120d070 we no longer use pkg-config. Fixes https://github.com/omar-polo/telescope/issues/9

According to gemini://geminispace.info, the search engine ha been shut down: The search provider geminispace.info has been shut down on 1st June 2024. Indeed, this seems to have happened prematurely but it is no longer serving requests. Therefore, switch to a different one.

Some gemini servers have faulty TLS handling, such as: gg: tls_close: EOF without close notify In such cases, telescope will receive that error and naturally assume there was a problem and stop processing. However, in the case of there still being legitimate content read from the request, this should still be displayed, rather than ignored. This change therefore detects this condition and adds a status of 'W' to telescope's modeline to indicate that the information presented is from a faulty gemini server and could be truncated and hence display oddly.

When building the bundled version of libgrapheme, don't build it in parallel, with "-j" is used to "make". In most cases, there's no guarantee that libgrapheme is going to be built before telescope, and the detection for this is such that it's always going to be called on-demand, which almost always guarantees that libgrapheme will be built after telescope.
